debian etch kvm no longer works

[RobFantini]

I think this started after a recent upgrade.
we have a debian etch kvm - that has worked forever.

now it boots slow and login is impossible.

the kvm wil lnot work on ceph or ext4 directory .

is there a way to start a kvm in debug mode to try to get to the cause of the issue?

 

[RobFantini]

could someone tell me how to mount a kvm disk?

[so I can copy files from the old debian 4.0 etch kvm to use on a etch lxc]

If the disk is in raw format you could use a loop mount and for qcow2 you must use qemu-nbd: see https://www.linuxunbound.com/2016/07/mounting-raw-and-qcow2-images/

that worked

mkdir /mnt/t01
modprobe nbd max_part=63
qemu-nbd -c /dev/nbd0   /nvme-ext4/images/117/vm-117-disk-1.qcow2
mount /dev/nbd0p1 /mnt/t01

thank you.
