@stevewest15 that is a shame! Thanks for sharing!

Were you able to work it out? I have a 32GB RAM domU that keeps failing migration between nodes unfortunately!

@john-c I am seeing an option for Migration compression in XO, under Xen settings on the Advanced tab for a Pool of 8.2.1 servers. Haven't tried it though.

@olivierlambert thanks for investing in this. Great news!

@olivierlambert this is a concern for me with moving to 8.3 - having a bunch of VMs just migrated from Xen with PV. I understand 8.3 doesn’t support PV and potentially some older operating systems. Will there be a page of supported OS / Distribution versions or have I just not looked hard enough for one that’s already there?

@olivierlambert thanks, my comment wasn’t meant as a criticism. I appreciate all you share so freely in both software and in the forums! Just was wondering how another user got on.

I have benefitted immensely thanks to Xen on bare metal over the years and while some people push towards KVM, I found the import process to XCP-NG very smooth once I got python2 built on the Debian12 dom0s that have served so well.

rdiff-backup was a really solid backup method for us using LVM snapshots and iscsi, so it’s just taking some time to get used to the GUI and the new CLI - and that the CLI can help resolve things stuck in the GUI. Your forums and personal posts are gold.

Automated boot testing after a backup is fantastic.

Thanks for everything!

@CodeMercenary Great question! Similar situation here. Sorry you didn't get a response.

What did you end up doing?

@mauzilla we've been running iscsi based backups with our previous 'bare metal' Debian Xen system, thanks to rdiff-backup. It worked really well for our purposes and I am still a bit uncomfortable with XO / XCP-ng backing up over a 1Gbps link. Hopefully a 10Gbps link will resolve that.

Have you considered using ZFS replication with TrueNAS as part of your backup strategy?

@mauzilla sounds like we are doing similar things! I gather you're now running TrueNAS Scale as we are? We decided to go with RC2 of Electric Eel since there's been some big architecture changes between 24.04 and 24.10.

We are just running it through testing and have run into performance issues for backups to an NFS target and I was interested to read the huge gain in speed you got from moving to iSCSI.

I was thinking of seeing if we can backup to an iSCSI target while keeping many of the VMs on NFS. Have you tried this and had any success?

@mauzilla It's been a few years, but this seems like a common issue. How have you worked around it?
