backup image .vma.lzo entpacken?

[ClusterX]

ich müsste eine KVM auf einen Hetzner Cloud (KVM) übertragen um die Ausfallzeit so gering wie möglich zu halten wollte ich ein .vma.lzo entpacken und im resque Mode auf den neuen Host per rsync kopieren, danach die fstab und networks anpassen etc.
Kann man ein .vma.lzo entpacken und wie?

after decompression you can use vma extract to access the raw data stored in the vma file.

thank you!
so is this action correct ?

lzop -d ./vzdump-qemu-108-2017_01_10-19_15_51.vma.lzo
vma extract vzdump-qemu-108-2017_01_10-19_15_51.vma /target/dir

looks okay - but should be pretty straightforward to test with a small backup

something does not work

lzop -d ./vzdump-qemu-101-2021_07_10-07_30_01.vma.lzo (OK)
./vma extract -v vzdump-qemu-101-2021_07_10-07_30_01.vma /backup/img
error while loading shared libraries: libproxmox_backup_qemu.so.0: cannot open shared object file: No such file or directory

installed pve-qemu-kvm as as described here:

any idea?

ok got it ;-)

apt install libiscsi7 librbd1 libgfapi0 libjemalloc2 pve-qemu-kvm mount
/sbin/losetup -P loop0 /backup/img/disk-drive-virtio0.raw
sudo mount /dev/loop0p1 /mnt

ok I guess I better use dd for the migration instead of rsync ...
would it be possible to convert a virtio0.raw or .vma.lzo into a .img format?

you need to install the missing library libproxmox-backup-qemu0

.img is not really a "format". if you want a raw image, then .raw is exactly what you want. a VMA archive once extracted also gives you raw image data. if you need a different format (like qcow2), qemu-img convert probably has you covered for all KVM/Qemu needs.
