Getting errors when migrating 4 out 5 VMGuest

If you don't restart xo-server after a rebuild, you won't be using the latest version you just did rebuild Let us know!

Hi, apologies for the late reply, I did restart XO and still have the same problem. Also just to make sure I have restarted both XCP-NG host as well and perform the migrate and still has the same problem.

@ashinobi You previously indicated that the migration worked from the VM screen. Is that still accurate?

Can you post a screenshot of your XO About screen so that we can confirm the commit in use?

ashinobi

@Danp

In regards to migration to vm screen, I confirm that is still working.

In regards to the screenshot of the about page:

I saw this morning there were 12 commits so I just updated to it as well.

Danp

@ashinobi That shows that you are on the master branch. You can confirm that by checking the output of git rev-parse --abbrev-ref HEAD (needs to be run from the correct directory ).

Did you forget to check out the alternate branch before you issued the Yarn commands?

ashinobi

@Danp

Here is what I got from running "rev-parse --abbrev-ref HEAD"

admin@xen-orchestra:/opt/xo/xo-src/xen-orchestra$ sudo git rev-parse --abbrev-ref HEAD
[sudo] password for admin:
xo5/fix-bulk-migration

It shows that I am using the alternate branch which is the "fix-bulk-migration"

Danp

@ashinobi Are you sure that XO is running from that directory? The commit shown above isn't included in xo5/fix-bulk-migration.

ashinobi

@Danp

As you know that I am using XenOrchestraInstallerUpdater script so I will be dependent on its config file. Base on the config file the installation is located at /opt/xo

# Base dir for installation and future updates
INSTALLDIR="/opt/xo"

so I assume that is the directory where XO is running and if I go to /opt directory there is only one folder in there which is "xo"

admin@xen-orchestra:/opt$ ls -ltrh
total 4.0K
drwxr-xr-x 4 root root 4.0K Feb  9 06:25 xo

If I check the status of "xo-server.service" it is pointing to the "/opt/xo" where it is running

admin@xen-orchestra:/opt$ systemctl status xo-server.service

@ashinobi That all looks fine. Probably just need to pull the source with git pull.

Also, I just took at look at that script and it seems that you can edit the BRANCH line in the config file to select a different branch for the script to use.

ashinobi

@Danp

do I change "Branch=MASTER" to "Branch=xo5/fix-bulk-migration"? to make it work?

Danp

@ashinobi I believe so

ashinobi

@Danp

Unfortunately I am still having the same issue. I have rebooted XO and both host as well:

Danp

@ashinobi That commit is still from the wrong branch, so I'm not sure what isn't working correctly on your end.

I just rebuilt my XO VM on that branch using these commands --

sudo bash
cd /opt/xen-orchestra/
git checkout xo5/fix-bulk-migration
git pull
yarn; yarn build
sudo systemctl restart xo-server.service

This is my About screen now, which matches the values I would expect for this branch --

ashinobi

@Danp

That is weird, if that is still from the wrong branch because when I ran the script it showed it is trying to download from the branch I specified:

I will try your method, unfortunately my backups for my VM Guest just kicked in so I'll update you once the backup has finished and I was able to run the command you have provided

@Danp said in Getting errors when migrating 4 out 5 VMGuest:

checkout xo5/fix-bulk-migration

When I did "git pull" I get the following:

root@xen-orchestra:/opt/xo/xo-src/xen-orchestra# git pull
hint: You have divergent branches and need to specify how to reconcile them.
hint: You can do so by running one of the following commands sometime before
hint: your next pull:
hint:
hint:   git config pull.rebase false  # merge (the default strategy)
hint:   git config pull.rebase true   # rebase
hint:   git config pull.ff only       # fast-forward only
hint:
hint: You can replace "git config" with "git config --global" to set a default
hint: preference for all repositories. You can also pass --rebase, --no-rebase,
hint: or --ff-only on the command line to override the configured default per
hint: invocation.
fatal: Need to specify how to reconcile divergent branches.

Do I need to merge any repository or ignore this?

Danp

Sorry, but I'm not sure what you should do at this point. Maybe you could reach out to the XenOrchestraInstallerUpdater
folks.

ashinobi

@Danp

That's fine, thank you for the help. I still have the migrate option when I go to the vm settings itself. Thanks for trying to help with my small issue and the information you shared about the use of git command

MathieuRA

Hi @ashinobi.
We have just pushed all the migration fixes from the xo5/fix-bulk-migration branch to the master branch. You should now be able to test it.

ashinobi

@MathieuRA

Thanks for doing the fix, I have tested this and I confirm it is working. I am able to migrate VMGuest to a different host by ticking the check box in the vmlist.
