"Block migraton" option on the VM´s Advanced tab

[manilx]

@abudef You can't migrate VM's between hosts and Disks between storages.

[abudef]

@manilx Thanks, how simple! I confused myself by thinking of "Block" as a noun, not a verb imperative, being influenced by the NBD term

[olivierlambert]

Ah yes I see, I wonder if we could make it more clear.

@abudef @olivierlambert @thomas-dkmt I agree. I read block the same way... how about disable or prevent. (French? empêcher)

[olivierlambert]

Disable or prevent are indeed a lot better.

[DustinB]

If I had my choice, Prevent Migration is more understandable.

Disable Migration, while it means the same thing, doesn't naturally come out of the English language.

Food for thoughts @thomas-dkmt

@olivierlambert @DustinB Thanks! It's always helpful to have a native speaker's perspective.

Happy to help, worth noting that if a setting like this is enabled on a given VM, there should also be some sort of visual indication on the home screen of XO to annotate that these VMs won't move unless this is disabled.

Done

@abudef The English translation is meant to be "Prevent Migration".

I think some lines were crossed ha.

I agree it really needs to actually read "Prevent Migration", that will then make it pretty clear.

[DustinB]

Looks to be correct on the current release of XO from Source and reads as "Prevent Migration"

Hi! Is there a VM parameter that saves this "Block migration" UI button?

I wasn't able to identify which one it is with command:

xe vm-param-list uuid=<VMuuid>

Thank you!

[olivierlambert]

I never remember the exact option myself, we should document it @thomas-dkmt

In the meantime, @Team-XAPI-Network can give the answer

How do you mean? Is the XO option not persistent?

XO sets these parameters:

# xe vm-list uuid=$UUID params=blocked-operations
blocked-operations (MRW)    : pool_migrate: true; migrate_send: true

Which you can set like this yourself:

# xe vm-param-set uuid=$UUID blocked-operations:migrate_send=true
# xe vm-param-set uuid=$UUID blocked-operations:pool_migrate=true

[olivierlambert]

It is persistent but people usually want to modify it manually in some cases Thanks @andriy.sultanov !

@andriy.sultanov Thank you for your answer! That's what I was looking for. I was looking directly at the VM parameters, with

xe vm-param-list uuid=$UUID

and I was directly searching for "blocked_migration". Now I know what to look for.

@olivierlambert Thank you for pinging the appropriate team for the answer.
