Erro r st art in g t h e g u est

When starting a configured virtual machine, an error occurs as follows:

# virsh start test

error: Failed to start domain test

error: internal error unable to start guest: char device

redirected to

/dev/pts/2

get_real_device: /sys/bus/pci/devices/0000:03:10.0/config:

Permission denied

init_assigned_device: Error: Couldn't get real device (03:10.0)!

Failed to initialize assigned device host=03:10.0

This error is often caused by a device that is already assigned to another guest or to the

host itself.

Erro r mig rat in g , savin g , o r d u mp in g th e g u est

Attempts to migrate and dump the virtual machine cause an error similar to the following:

# virsh dump --crash 5 /tmp/vmcore

error: Failed to core dump domain 5 to /tmp/vmcore

error: internal error unable to execute QEMU command 'migrate':

An undefined

error has occurred

Because device assignment uses hardware on the specific host where the virtual machine

was started, guest migration and save are not supported when device assignment is in use.

Currently, the same limitation also applies to core-dumping a guest; this may change in the

future.
