Guest cannot start.
I have a KVM guest that has failed.
It was working before, i shut it down to take a latest snapshot, but when i run it, it fails with below errors:
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/engine.py", line 588, in run_domain
vm.startup()
File "/usr/share/virt-manager/virtManager/domain.py", line 150, in startup
self._backend.create()
File "/usr/lib/python2.6/dist-packages/libvirt.py", line 300, in create
if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: operation failed: failed to retrieve chardev info in qemu with 'info chardev'
I have other guests on the same VM Host and all are working.

Any one with a solution/work-around i will greatly appreciate.
Same here. I allocated this problem while doing PCI pass-trough.
