As title, Does AOS 6.x support Fault-Tolerance on ESXi 7.x ?If positive, does it support more than 4 FVTM in an ESXi 7 host ?   I had read https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-57929CF0-DA9B-407A-BF2E-E7B72708D825.html . Can I change parameters to support more than 4 FTVMs in an ESXi host?

Hi, One of my employees deleted 2 VMs with the name like xxxxxxxxxxxB1234 and xxxxxxxxxxxxxB1235 and at the same time xxxxxxxxxxxxxT1234 and xxxxxxxxxxxxxxxT1235 were deleted. (Logs show that he deleted them like less than a minute later) He claims that he did not touch those two. Is it possible that two VMs can be corelated somehow and deleting one triggers deletion of another one? One was bench and one was test. The only difference in name was one letter.

nutanix ERROR ipv4config.py:1811 Unable to get the KVM device configuration, ret 1, stdout , stderr br0-backplane: error fetching interface information: Device not found\n Anyone know what to do with this error.  I turned on remote syslogging to see why a host has been crashing and I see this as one of the errors in the logs.  The host is a Dell PE R630.Not sure if KVM means the host OS, since AHV basically is KVM or an actually connecting to iDRAC for Keyboard Mouse Video.  

What metrics are considered when Acropolis Dynamic Scheduling makes a migration decision on AHV related to CPU usage? Does ADS consider only CPU usage on the Host? Or does ADS take into consideration other VM or Host metrics such as CPU Ready, Co Stop, and/or Steal Time?

Howdy,We have a VM that is licensed by hardware. We needed to do some after hours work on the network so we shut down the VMs and cluster. When it came back online the software unlicensed itself.Looking at the 4th bullet point has be wondering from this KB: How to set MAC address for VM NIC on AHV clusterNot finding much luck to my question but I was curious if the NIC MAC changes if it moved from one node to another when it came back online?Also, is there anyway to see if the system had a prior MAC NIC?Thanks,

Hi,We recently upgraded to AOS 6.5. We’re looking for a command to run to monitor the version of AOS Security, since we noticed it was a new component in LCM. I’m assuming it would be on the CVMs.

Hello,I am conducting a test using NX-3050 equipmentI know it's an old Node-Model and I have previously installed it with AOS 5.20.2.1As you can see now, we are going to test the upgrade using LCM in AOS 5.10.11.1LCM was installed as shown using 2.5.0.2.32663 Dark-site​​​​​I uploaded the file 5.20.2.1 because I saw the opinion that if the AOS version for upgrade is EOS,it might not be displayed on the screenNo matter how long I wait for the LCM in the setting window, there is no screen, so should I reinstall it? I think I saw the opinion that the AOS version was modified because it was low, so is it impossible to update using the LCM DARK site? Thank you for reading the long article and I would really appreciate your opinion

Dear All,New to Nutanix Frame here. Hence, please just let me know if I left out any essential information.We are running a non-persistent account on Frame. We noticed that AD objects that are related to instances that have been removed from the Frame account, e.g. by manually terminating them from the Status page, remain in AD. The expectation would be that these would be purged automatically. We used the Nutanix Frame AD Helper to verify that the service account does have the necessary permissions. Also, we are seeing that new machines are being created without issues.

Hi,I just want to ask if its possible to use the 1 GbE interface while using the 10 GbE for back up network in case the 10 GbE switches fails, if its possible how to set it up?

CVM On LACP networks, Physical switches use MLAG technology，CVM bandwidth performance cannot be improved, and the maximum can only be 10Gb.
