How to Download IOS Files from Nutanix AHV Cluster

If you're working with a Nutanix AHV Cluster and need to download IOS files, here's a step-by-step guide to make the process seamless.Step 1: Connect to CVM via SSHOpen a secure shell (SSH) session to one of the Controller Virtual Machines (CVM) in your Nutanix cluster. Use the following command:ssh nutanix@<CVM-IP-Address>Step 2: List Available ImagesOnce connected, use the Nutanix Acropolis Command Line Interface (acli) to list available images:#acli image.listStep 3: Copy Image UUIDIdentify the IOS image you want to download and copy its UUID.#acli image.get <Image-UUID>From the results, copy the vdisk_uuid associated with the desired imageStep 4: Download Using WinSCPDownload and install WinSCP, a popular file transfer tool. Connect to one of the CVM IP addresses on port 2222 using the SFTP protocol. Ensure that you use the username 'admin,' not the Nutanix CVM username.Navigate to the container and locate the disk image corresponding to the previously copied vdisk_uuid

What is ICAP and integration with Nutanix files

ICAP stands for internet content adaption protocol is an open standard being adopted to connect devices to enterprise-level virus scan engine . same way with the nutanix files is to enable communication with external servers hosting third-party anti-virus software to scan inbound data (files) in transit via Secure Proxy before sending it to the backend destination server.ICAP WORKFLOWThe ICAP service runs on each Nutanix Files file server and can interact with more than one ICAP server in parallel to support horizontal scale-out of the antivirus server. The scale-out nature of Files and one-click optimization greatly mitigate any antivirus scanning performance overhead. If the scanning affects Nutanix Files FSVM performance, one-click optimization recommends either increasing the virtual CPU resources or scaling out the FSVMs. This feature also helps both the ICAP server and Files scale out, ensuring fast responses from the customer’s antivirus vendor WHY Nutanix files integration with

Change Nutanix AHV NIC From access Mode to Trunked Mode

Trunked Mode allows multiple VLANs on a single NIC for VMs that are VLAN aware.by default, NIC cards are in access mode.mode can't be changed from the UI (Prism) and the solution is to update from CVM acliyou can also covert exiting NIC card to Trunked Mode however based on my experience best and easy way is to add a new cardStepsSSH CVM acli <acropolis> vm.get VMNAME copy information in notepad nutanix@CVM~$ acli vm.nic_create <vm name> network=<network name> trunked_networks=<comma separated list of allowed VLAN IDs> vlan_mode=kTrunked example:-vm.nic_create VT-LAB-1 network=NETWORK0 trunked_networks=2021,2022 vlan_mode=kTrunkedWHY Trunked is Required Above Setting is required when the virtual machine needs to create multiple networks on a single interface. in my case it's WAF devices that are configured for multiple VLANs, each VLAN is associated with a different kind of applicationif you want to add more VLANs run the belowvm.nic_update TT-WAF-01 00:68:8

Cross Hypervisor Disaster recovery ESXi To AHV or AHV to ESXi

Cross hypervisor disaster recovery (CHDR) provides the ability to migrate the VMs from onehypervisor to another (ESXi to AHV or AHV to ESXi) by using the protection domain semanticsof protecting VMs, generating snapshots, replicating the snapshots, and then recovering theVMs from the snapshotsKey notes install and configure NGT on all the VMs When you recover VMs from the AHV hypervisor on the ESXi hypervisor, the VMs come up with E1000 NIC attached by default. However, if you want to bring the VMs up withVMXNET NIC is attached, you must install VMware Tools Static IP address preservation is not supported for CHDR workflows. If a VM has an astatic IP address configured, you must manually reconfigure the VM IP address after its recovery on the target site. Hypervisor-specific properties like multi-writer flags, independent persistent and independent non-persistent disks, or changed block tracking (CBT) is not preserved in the CHDR operation RequirementsNutanix supports only VMs with
