Hi guys
I'm trying to connect to an encrypted image but my
fiddling - as I never known this one - fails.
Very bare cmd fails:
-> $ qemu-nbd --connect=/dev/nbd0 /00-VMs/enc.ommie.qcow2
qemu-nbd: Failed to blk_new_open
'/00-VMs/enc.ommie.qcow2': Parameter 'encrypt.key-secret'
is required for cipher
so I tried:
-> $ qemu-nbd --connect=/dev/nbd0 /00-VMs/enc.ommie.qcow2
--object
encrypt.key-secret=bl........................................
qemu-nbd: Parameter 'qom-type' is missing
and so on I continued to no avail and soon gave up, in
hope that some wizard has already a working cmd.
many thanks, L.
If anybody else might need this/similar then something like
this should work:
-> $ qemu-nbd --connect=/dev/nbd0 --object
secret,id=my-sec0,file=/etc/libvirt/secrets/my-secret.base64,format=base64
--image-opts
driver=qcow2,file.filename=/00-VMs/enc.mastercommie.qcow2,encrypt.format=luks,encrypt.key-secret=my-sec0
