We've been getting bug reports like the above against virt-manager for a
while now: installing new VMs consistently throws an error 'Timed out
while reading monitor startup output'. The user can then just retry the
install and it will go off without a hitch.

I only just realized that the common thread between the reports is
physical install media: apparently the qemu monitor isn't too responsive
while it's waiting for a cold cd drive to spin up.

The attached patch jacks up the timeout from 3 seconds to 10 seconds
when doing the initial monitor read. I verified that this fixes the issue.
