AHV Virtualization

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.

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

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

I migrated several Windows VMs using Nutanix Move.After the migration, I noticed that the network configurations of some VMs do not match the source settingsIPv6 protocol: Disable → Enabled I checked KB-10818, but it doesn't seem to apply to my case.(Move degraded?) Network location: Public → Private (or Private → Public) Windows Firewall: Disable → EnabledWhy are these settings changing during migration? Environment:AOS: 6.10.1(Source) → 6.10.1(Target) Hypervisor: AHV 20230302.103003(Source) → AHV 20230302.103003(Target) Guest OS: Windows Server 2019 Nutanix Move version: 6.0

Hello,Today I have delivered a three node Cluster to customer.Cluster was Set Up a few days ago in my Environment with a flat Switch.Bond mode for both vswitches is active-backup.Unfortunately Customer had prepared his ToR switches with LACP.All hosts and CVMs cannot communicate.What is the recommended procedure to fix ist?Change bond Mode host by host with manage_ovs  OR Let network team configure the switches (disable LACP) and configure the clusternodes via Prism, after that let Network Team enable LACPKind regards,Thomas

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?

Hi,I am trying to deploy an AHV cluster using Nutanix Foundation VM against HPE DX380 G12 servers with iLO7, but the deployment consistently fails in Phase 1 during "Preparing installer image".The relevant error in the VM Foundation log is:Imaging requires Foundation HTTPS to be enabled on port 8001 for nodes that require HTTPS boot media.What I have verified so farOn the Foundation VM:firewalld is not running port 8000 is listening port 8001 is not listening at all curl -vk https://127.0.0.1:8001 returns connection refused curl -v https://127.0.0.1:8000 returns wrong version number, which seems to confirm that port 8000 is only serving HTTP

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

We have created Auto shutdown playbook of AHV host with scheduled but facing issue, when Prism Central ON , these scheduled initiated before time and we not  able to to access prism central , so disable  playbook task. Prism element started then PC started and excuted these playbook schedule and shutdown 2 AHV from Prism cluster.

Estimado Foro,En relación a los procesos de migración donde el E2E, los procesos, flujos, ambitos incluso de permisos es un factor que limita y afecta una correcta migración.Queria consultar si alguien ha realizado algun documento de migración donde incluya: restricciones, compatibilidades, recomendaciones, el año anterior realice una migración en este ambito que me da un contexto inicial, sin embargo el reto es grande cuando todo incrementa en tamaño de Workload y criticidad, en este sentido si alguien tiene algun inicio seria importante lo comparta, o en su defecto lo ire documentando para aporte a la comunidad.Una consulta: alguien ha expermientado migrar un Active Directory to AHV, de pronto me puede compartir su experiencia? 

Hi,I have recently deployed a pair of AHV clusters on a customer. Each cluster has its own Prism Central cause they are going to be part of a Metro availability environment with a witness VM on a third site.Now the customer is asking me if he could have some kind of overview and managing of both clusters from a single dashboard.I think that Nutanix Central could accomplish that request, however I’ve never deployed it and I have some questions.Checking the documentation I see that you can deploy it onpremise by downloading it from each Prism Central marketplace. So I assume it will deploy a VM appliance on each cluster (similar to prism central) and I should have to config it.Are there any specific tips that you could provide before deploying it?By the way, both clusters have PC 7.5.0.5 and AHV 11, everything is up to date, so I assume there is no incompatibility with nutanix central.T
