[libvirt-users] Qemu restore error

[Dennis Householder]

Hello,

I'm not sure if I am having a kvm/qemu issue, a virt-manager issue, or a 
libvirt issue, so if I am asking the wrong crowd please let me know! In 
short, restoring some suspended kvm guests via virt-manager is failing 
because libvirt cannot read the qemu header. I cannot find any 
documentation on what this means. From virsh's limited documentation I 
was able to gather that there is probably something wrong with an xml 
file somewhere, but I cannot find it. Any advice is greatly appreciated!

Synopsis:
I have 5 KVM guests on a Fedora 16 laptop host. I manage them locally 
through virt-manager. These guests are JUNOS 10.1R1 (installed over 
FreeBSD 4.1 mini-inst) on a patched bios (SeaBIOS 
pre-0.6.1-20100805_064324-Compaq8510w). One time I suspended my laptop 
and the kvm domains were suspended as well. Trying to restore yields the 
following error:

Error restoring domain: operation failed: failed to read qemu header

Traceback (most recent call last):
