Hi,

I've noticed an issue with live migration on VMs that were imported from VMware using XO. During migration, the VM hangs and loses network connectivity (ping fails), requiring a forced power-off and power-on to recover.

Here’s what I’ve found:

1. The VM template after import is incorrect, it shows as "Other install media".
2. If I create a new VM using the correct template and reattach the existing VDI, the issue is resolved. I can do live migration without issue.

Please let me know if further investigation is needed or if there's a recommended fix for the template mismatch during import.

Best regards,
Azren

I've already moved the pool master from host #1 to host # 2

It appears that the issue is related to Host #1. Any migration into or out of Host #1 tends to cause problems. Occasionally, virtual machines (VMs) lose network connectivity during migration and become unresponsive — they cannot be shut down, powered off (even forcefully), or restarted, often getting stuck in the process.

I’ve added Host #3 to the pool. Migration between Host #2 and Host #3 works smoothly in both directions.

Any idea how can I kill the stuck VM?

xe vm-reset-powerstate force=true vm=MYVM03
This operation cannot be completed because the server is still live.
host: cb8311e8-d0fd-4d53-be99-fe3fea2c9351 (HOST01)

Both hosts are Dell PowerEdge R760 dual processor with 512GB of memory. Missing this month patches. I'm trying to live migrate VMs to 1 host so that I can start installing patches and reboot.

Host#1

Host#2

Host#1: dmesg

Host#2: dmesg

My dmesg...

This is the XO VM that I try to migrate, but issue also happen to other VMs running MS WIndows.

@olivierlambert

This happens to other VMs as well.

1. Check your OS is having static RAM settings and enough RAM

   Yes
   

2. Do you have tools installed in your OS?

   Yes
   

3. Time sync between the hosts?

   Yes

Anything else I can check?

Hi,

I'm having issue with live migration between xcp-ng host in a pool. The migration looks ok. The VM migrated to Host #1 from Host #2, but the task stuck at 57% (Async.VM.pool_migrate stuck at 57%). I have to restart the toolstack to make the tasks go away. Any idea?

I'm using XO from source and on the latest commit.

Thank you.

Best regards,

We use clonezilla method and migrate 100 over VMs with about 15TB of VDI in 2 weekends.
