Nutanix Cloud Infrastructure

Hello Since onw month, when change some VMs, of Data Protection to Ptotection Policie, show the next alerts: VSS is enabled, but Nutanix VSS provider or pre_freeze/post_thaw scripts are not installedVSS snapshot is not supported for the VM X because VSS software is not installed.I returned some VMs to Data Protection, and the alerts did not return.Why do it pass this behavior?

Hi team, quick question: Is it supported to mix NICs on the same node? Specifically, can both the Mellanox 2-port CX5 SFP28 (25G) and the Intel 2-port E810 SFP28 (25G) (E810-XXVDA2) be used together on a single node?

Hi All,I’m developing a script to move away from GUI LCM click-ops for our Prism Central instances, I’m having some trouble with the lifecycle V4.1 namespace.https://{pc-ip}:9440/api/lifecycle/v4.1/operations/$actions/compute-recommendationsI’m getting errors trying to POST the following data. I understand recommendationSpec expects the UUID and targetVersion but I simply can’t get this to work, any suggestions?I’m following this documentation → https://developers.nutanix.com/api-reference?namespace=lifecycle&version=v4.1I have both a NTNX-Request-ID and X-Cluster-ID in my request, I recieve a a 400 bad request response.{ "recommendationSpec": [ { "entityUuid": "<LCM-uuid>",

Hello Team,I have recently deployed a Nutanix solution, and everything is working as expected. I have also deployed a virtual machine with the Veeam Backup solution, which is running successfully.I have an external USB HDD that I would like to map or make accessible within the VM as a storage. Could you please guide me on how this can be achieved?Thank you for your assistance.

i  have two cluster  main  cluster  and DR cluster , what  is the best practice to upgrade two cluster , can i start with main or DR first , what about replication  it is effected with upgade? 

Hi community,I'm in the middle of deploying a 3-node Nutanix AHV cluster and have a question about live migration traffic behavior with and without the Backplane LAN configured.My current setup:- 3 Nutanix AHV nodes- 10G SFP+ uplinks for VM traffic (VLAN 1 - e.g 10.10.100.0/24)- 1G RJ45 uplinks for DMZ and Corp networks on separate VLANs- Backplane LAN not yet configuredMy questions:1. Without the Backplane LAN configured, when a host is placed into maintenance mode and VMs are live migrated to other nodes,  does that migration traffic travel over the VM's own network? For example, if a VM is on my DMZ network (1G), does its live migration traffic also go over that 1G link?2. Once the Backplane LAN is configured on a dedicated VLAN (e.g. VLAN 10 - 192.168.10.0/24) on my 10G uplinks, will ALL live migration traffic route over the backplane regardless of which network the VM is connected to?3. Is there any official docu

I am setting up recovery plans for disaster recovery between our two clusters. I have been through the documentation multiple times, and I still am confused by the test failover/failback subnets that are configured as part of the recovery plan. Production is easy. We have the primary cluster in one location in Subnet A. We have a recovery cluster in another location in Subnet B. I just set the production subnets to be Subnet A and B at each location respectively with their matching gateway and prefix. The Test Failover/Failback subnets continue to confuse me. The documentation indicates they should be isolated and non-routable subnets which makes sense. But WHERE are those subnets defined? We use external IPAM. Each cluster is connected to a core switch stack at its location. We have a few different subnets/VLANs defined on those core switches, with a defined IP range, /24 in each case. All VMs have static IP addresses, though the core switc

 Good morning all, i have the problem, that one CVM out of a 3-Node-Cluster drives me crazy… For some reason, the CVM went unresponsive regarding it´s cluster-services… CVM itself is available via SSH and I´m able to login using the Nutanix-User CVM cluster status says:   nutanix@NTNX-xxx-B-CVM:172.18.95.76:~$ cluster status | grep -v UP2026-05-08 04:50:48,386Z INFO MainThread zookeeper_session.py:226 Ignoring passed host_port_list: zk1:9876,zk2:9876,zk3:9876 because the passed host_port_list appears to have been copied from the environment variable or gflag.2026-05-08 04:50:48,387Z INFO MainThread zookeeper_session.py:296 cluster is attempting to connect to Zookeeper (unestablished session (object 0x7f6bd2b5d220)), host port list zk1:9876,zk2:9876,zk3:98762026-05-08 04:50:48,387Z INFO MainThread patterns.py:75 Creating a new instance for ZookeeperSe

I'm trying to deploy Prism Central (PC) from Prism Element (PE). Previously, I had registered a PC to the cluster and then unregistered it to redeploy a new one.However, during the new deployment, at the “Size and Scale” step, no selectable options (Small/Medium/Large) are shown — only the description text appears.Current situation:No dropdown or selectable options available No explicit error message Cluster is running normallyI'm not sure if this issue is related to the previous register/unregister of PC, or due to resource constraints, version mismatch, or a UI issue.Has anyone experienced this after unregistering PC? Is there any cleanup required on the cluster before redeploying Prism Central?

Hi Experts !We recently upgraded one of our Nutanix clusters to AOS 6.8.1.8 and started facing an issue with the Cerebro service shortly after.Symptoms observed:Remote replication alerts after the upgrade.Remote site configuration warning indicating that some CVM/SVM IPs were not properly configured on the peer site.Cerebro entering a crash loop?cluster status showing constantly changing/high PIDs for Cerebro.cerebro.FATAL reporting an error similar to: Check failed: citer != (pd.second)->snapshot_uuid_map().end() with a snapshot stuck in a pending action.It looks like there is a stale or orphaned snapshot operation in the WAL / metadata, likely triggered after the upgrade while replication configuration was not fully consistent.Has anyone already seen this behavior after an AOS upgrade?Did you resolve it by fixing the remote site configuration o

Hello everyone,I am planning a migration from VMware to Nutanix AHV.The environment still includes some legacy operating systems, such as:Windows XP / Windows Server 2003 Windows Server 2008 (non-R2) Very old Linux distributions (kernel 2.6 era)I fully understand that:These OS versions are not supported on AHV Migration is technically difficult and not recommended This would be a best-effort / temporary solutionHowever, due to VMware licensing constraints, the customer must exit VMware and migrate these VMs anyway.My question to the community is simple:👉 In this kind of situation, what has been the most effective or realistic approach you have used to migrate legacy OS VMs from VMware to AHV?Any real-world experience or advice would be appreciated.

I recently deployed Nutanix , but when I am opening web browser it is showing and I belive that it might be the certificate issue. I issued a commad to check the certificate in CVM and it is showing below and my system team already passed the date and time, what might be the other issue. Cluster is showing UP and healthy.  upstream connect error or disconnect/reset before headers. retried and the latest reset reason: connection failure, transport failure reason: TLS error: 268435581:SSL routines:OPENSSL_internal:CERTIFICATE_VERIFY_FAILED

Are we able to configure a recovery plan in Nutanix Leap when we have Production and DR clusters (10 Clusters each) managed across two separate PCVMs (both running version 7.5.0.5)?Currently, while creating the recovery plan, I can select individual VMs, but I do not see an option to select at the cluster level. Is this expected behavior when using two PCVMs, and how can we properly configure a recovery plan in this setup?Any guidance on achieving this design would be helpful.

Hi I have a customer that is asking me for some feature on Nutanix (AHV) that may provide some kind of immutability for the VM snapshots, so in the event of an admin account hack the snapshots could not be destroyed.I was looking for something like that on AHV and I discovered Secure Snapshots with Approval Policies in Prism Central and I’d like to confirm a few points regarding requirements and licensing.https://portal.nutanix.com/page/documents/details?targetId=Disaster-Recovery-DRaaS-Guide-vpc_7_5:ecd-approval-policies-dr-pc-c.htmlContext:The customer has two AHV clusters, each one with his own Prism Central Licensing: NCI Pro + Advanced Replication add-on (

Hi,I’m looking to deploy the L4 load balancers for domain controller services LDAP(S), NTP, & DNS, you know they type of thing that gets addresses programmed into devices/applications.I can create a LB session for an IP and have it listen on multiple ports 53,123,636 but when I gets round to selecting the destination VM Nic's I can only specify a single port for the destination.  Is there any way to balance multiple services from a set of hosts with a single VIP, or will I need to create an LB session and separate VIP for each of the services?Also some of the documentation i read said that It’s possible to use VM Categories to select the destination VM’s, but I don’t seem to have that option, which version do I need to be running to get that?

Hello, I have recently deployed nutanix with Foundation, and every went well and I can access the PE from web browser. But when I go the Virtual Switch section, I cannot See vs0 in Switch Tab, not sure what is the issue. I go to Cluster Setting and Reboot the cluster, but it keep on processing and so on entering in maintenance mode. Can anyone help.    Regards

Cloud-based disaster recovery with Nutanix MST (Multi-cloud Snapshot Technology) gives organizations a cost-effective way to replicate VM snapshots to object storage targets like AWS S3, Azure Blob, or Nutanix Objects and recover workloads when it matters most. Object storage is purpose-built for durability and geographic distribution, which makes it an ideal replication target. The trade-off has always been recovery speed: pulling data back from object storage to the AOS cluster is slower than reading from local NVMe or SAN-backed storage, and for large workloads that gap translated into hours of hydration time before a recovered VM could power on. For latency-sensitive workloads including clinical applications, financial systems, and operational databases, that recovery window was the one remaining challenge to address.Nutanix Instant Restore changes the equation for MST-protected workloads. Now generally avai
