Live migration - Same pool, multiple SR´s

iLix

Live migration of a VM to one of the other hosts in the same pool puts all VM-disks on the default SR, can I avoid this somehow? I can turn off the VM and boot it on one of the other hosts, but thats not what i want

jedimarcus

Is your SR shared yes?

This is not normal, I'm moving VMs all the time... they don't move SRs

@jedimarcus

The SR-s are shared, FC and NFS. So a mix of thick and thin. Running the latest 8.1, XOA from sources and it was updated this weekend.

Your problem is unclear. Can you explain the steps you are doing, and the result vs the expected result.

Migrate to a host in the same pool:
Step 1.png
After: The VM disks have been moved to the default SR
Step 2.png
Expected result: VM should be moved to the other host, but disks should stay on the NFS shares.

olivierlambert

That's weird. In theory, if the disks are shared, there's no move. Can you show us how do you fill the migration pop up?

jedimarcus

@ilix Can you show what your "Migrate" popup looks like? Does it show VDI switch options?

I wonder if this is somehow related to the issue I reported here

olivierlambert

And what about migrating the VM with xe CLI and compare the result? If it's different, then it's clearly a wrong XO behavior.

@olivierlambert

 xe vm-migrate vm="Debian Demo" host=IBM-02 live=true

This gives the expected outcome

olivierlambert

Okay great! So it's an XO problem. Can you open an issue explaining the problem? There's already a template: https://github.com/vatesfr/xen-orchestra/issues/new

@olivierlambert

With the newest XO build from sources:

a776eaf61
xo-server 5.70.0
xo-web 5.74.0

Hosts are running latest 8.1

It is now working, from XO and cli

olivierlambert

What was your previous XO version? An old one?

Thats when I ran the builder before the currently installed one.
