HiI have an intermittent issue where VMs can’t contact VMs on other hosts. I’m trying to find a pattern with timings and the hosts involved but haven’t found one yet.When a VM can’t reach a VM on another host, the problem can be resolved by migrating the VMs to the same physical NX hoste.g. VM1 on Host1 can’t reach VM2 on Host2, workaround is to migrate VM2 to Host1This leads me to believe there is a problem with the network between hosts. Each host has 2 uplinks going to 2 switches with active-active load balancing and my current theory is the problem lies with the aggregation. Perhaps packets are leaving eth2 and returning on eth3?I’m going to change the OVS bond mode from Balance-TCP to Active-Backup and see what happens. I don’t need the throughput of 2 active links so perhaps this should have been the config from the startQuestion - has anyone else seen this behaviour on your cluster? Environment:4 node clusterUplinks to 2 Cisco Nexus switches aggregrated using Balance-TCP
HiWe have a cluster running on AHV and have recently found that its not possible to host guest VMs running Hyper-V within them, as a layer 2 hypervisor.The scenario is we have a few Windows 2016 VMs running on ESXi at the moment and each VM has the Hyper-V role installed in Windows 2016, providing containers for Docker.We want to move the VMs to our Nutanix cluster but running Hyper-V within a VM is not a supported type of nested virtualisation.Support say there are only 2 types of nested virtualisation supported: Credential Guard and WSL2.Docker is able to use WSL2 for containers as an alternative to Hyper-V but our problem is we need to stick to Windows because our apps are coded for Windows and our Dev team are not keen on re-writing everything!I’m looking for an unofficial workaround, is there a way to force AHV to allow in-guest layer 2 hypervisors to run? Its possible on ESXi, it feels like there should be an option in the host’s BIOS to enable compatibility.Any ideas would be
HiI have a question about VM snapshots. I dont think this is possible otherwise I’m sure it would be obvious in PE or PC but I’ll ask anyway:Can we snapshot the VM’s active memory? i.e. include the active OS memory in the snapshot, the equivalent of ESXI’s .vmem fileI’ve read up on crash vs application consistent snapshots but I dont see a mention of capturing the OS memoryThanks
