@RobWhalley I think in the beginning i had that option enabled in my backup jobs, but found it was a hassle to move VMs between hosts with it on so i turned it off for all backups. Might be why my jobs worked because i had already done that switch in the past.

posted in the other thread as well but Xen Orchestra, commit 1a7b5 backups are working again. I tested configure and vm backups. They are being backup to NFS share.

updated on my three servers no issues.

try downgrading your nfs to use version 3. I think version 4.x has performance issues.
in you settings-->remote, you can edit the nfs mount for backups and add in the -o options section.

I dont know the exact command but you can try using nfsvers=3 and see if that helps.

scratch that prior comment. My backups are all setup as delta backup with schedule 2nd run that forces full backup. So i believe both are working correctly.

if you can also try deleting all the backup snapshots of the VMs in the backup and running full backup then the delta backup jobs.

looks good

thanks for quick fix

@tc-atwork thanks for post, i wasnt able to get xo6 setup as i havent had time to play with it. I look forward to when it released. For now I just keep using xo-lite to open the console window.

@olivierlambert

I will have to figure out how to get XO 6 up and running.

just for reference. Under console tab in XO you have all the extra around the display

which is fine for quick access to do something but becomes a hassle when trying to work with the vm display.

XO lite open in a new tab is clean interface. And it expands with the broswer.

PS looking forward to the copy/paste feature being implemented.

@probain I tried that just now, not really doing anything in XO. I am under console tab on a VM.

On a side note, seem like the url for the new tab function in xo lite is

https://MasterHostIP/#/vm/5de057e5-97a0-937f-15d6-ef8793c54331/console?ui=0
Maybe because of the IP being the host and not XO it may be harder to implement as a button on XO?

I found under XO lite the open console in new tab an awesome feature. Its better then remote desktop especially for linux based VMs. I would like a button to provide the same feature in XO if possible.

Maybe somewhere in this group of buttons.

Mine seems to work okay.

Xen Orchestra, commit 1c01f
Master, commit 1c01f

updated on my three servers no issues.

so it seems like when i make the igpu pass through, i see the starting lines of xcp-ng but it never gets to the console screen. which is what i expect.
When I add the pcie devices (igpu/hdmi audio) to a vm and start it up, I get and update to the screen and it shows a red number counting which is part of the console.
So it seems that when the VM re-initializes the igpu, dom/xcp retakes it over.
I confirmed that by using the keyboard to move around and it reshowing the console and filling the missing details as i move around.
So why is the dom/xcp retaking the video device over again when it should be blocked from accessing it?

is there anyway to block igpu from being used by xcp-ng during boot? I have it setup for pass through but it fails under the VM. I think it because xcp-ng still displaying the console screen and does not want to give it up.

I wrote a simple script to help those of us who want to do pci passthrough and running into xe limits.
Not responsible for issues/use/etc... use at own risk.
Feel free to github/maintain it, i wont be planning on doing any more on it.
I did this to work with pci passthrough and issues i been having while testing a new build. I found out that adding new devices while enabled pci for devices showing in xe can lead to issues and having to do pci hide reset. So i added that. I also added a enable pci device that is on xe so you can do it via app on host or still do it on gui using XO. Finally added a menu to add non xe pci device directly to vm.
Vm list is my list so you need to update that with what you want to enable.

Hope this helps someone else

So grab the code, save it to /root/pcishare.sh and chmod +x it to run it.
This is on the host directly.
