Fwd: how to convert virtualbox vm instance to kvm instance, and then run kvm instance under virt-manager?

["Qiubo Su (David Su)" <qiubosu@xxxxxxxxx>]

dear community,

no matter the guest vm instance is raw or qcow2 format, when run "virsh dumpxml <guest-name>", the error are all the same, shown below:

virsh dumpxml ttylinux.img
error: failed to get domain 'ttylinux.img'
error: Domain not found: no domain with matching name 'ttylinux.img'

virsh dumpxml cloud.qcow2
error: failed to get domain 'cloud.qcow2'
error: Domain not found: no domain with matching name 'cloud.qcow2'

it is much appreciated if you can help to identify the problems.

thanks,
david su

I'm guessing this is because libvirt still thinks the format of the
disk is raw instead of qcow2.  What is the output of:

  virsh dumpxml <name-of-the-guest>
