What's the size of the virtual disk for this VM?

Are you sure it's the disk size and not the space used in the VM? That's very different in thick SR.

For the first screenshot, it's pretty clear that's the issue. For the second one, it's a different problem. Are you using XO from the sources or XOA?

@livierlambert all my VMs have same disk size, inside VM I attach iSCSI drive - that drive is big but it is not part of the backup.
I use XO from sources. Both screenshots are from same backup job, just different sections - one from tick on the fail icon inside backup page and second is inside settings -> logs

SO I have upgraded to latest version of open source version of XO. I am currently at:

xo-server 5.111.1
xo-web 5.114.0
build afadc - https://github.com/vatesfr/xen-orchestra/commit/afadc8f95adf741611d1f298dfe77cbf1f895231
also latest version of backup proxy

I try the restore, same result, here is the complete log (from settings -> logs):

backupNg.importVmBackup

fix(read-chunk): better not enough data error message

florent

@amjank

Fist : to help you get your file as fast as possible:
since ths is a full vm backup, tha data are stored in a .xva file in <your remote>/xo-vm-backups/<uuid of the vm>/<date of the backup>.xva datetime of the backup can be a little different, depending on your timezone

this file should be importable through the import VM feature of XO

then , to understand the root cause: are you restoring through the proxy ?
Is there anything related in the xo logs ?

If nothing will help and you can't import xva with import VM, I have solution.

Deploy new VM with disk x4 times greater than backup file. OS Ubuntu 16.04 or later.
Copy backup. Take attention. You need always copy backup. Do not move it.
Install xva-img https://github.com/eriklax/xva-img

add-apt-repository ppa:ubuntu-toolchain-r/test && apt-get update && apt-get install -y gcc-7
cd to xva-img dir and run next command
cmake ./
make install

Extract xva file

tar -xf my-virtual-machine.xva -C my-virtual-machine
chmod -R 755 my-virtual-machine

In folder my-virtual-machine you will find some directory like Ref :1, but maybe with another number. Remember this number.
Create raw disk from extracted. Replace 1 with number from previous step.

xva-img -p disk-export my-virtual-machine/Ref\:1/ disk.raw

Install qemu-utils

apt install qemu-utils

Convert raw to vhd

qemu-img convert -f raw -O vpc disk.raw [vhd-name-you-like].vhd

Copy vhd to some SR. I'm using local SRs, so in my case path is /var/run/sr-mount/[sr-uuid]
Go to the host, cd to SR folder, get VHD uuid, rename VHD

cd /var/run/sr-mount/[sr-uuid]
vhd-util read -p -n [vhd-name-you-like_from-step-8].vhd
mv [vhd-name-you-like_from-step-8].vhd [uuid].vhd

Rescan SR
Attach VHD to existing VM or deploy new one
Get you files

wow. I am getting on with this in parallel. Thank you again! Results for both suggestions and requests are coming!
