Thanks. I added
<parallel type='pty'>
<source path='/dev/lp0' />
<target port='0'/>
</parallel>
to the <devices> section of the relevant file in /etc/libvirt/qemu. The
parallel "hardware" shows up in virt-manager, but with - as the source
path; running the domain yields
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/engine.py", line 531,
in run_domain
vm.startup()
File "/usr/share/virt-manager/virtManager/domain.py", line 380,
in startup
self.vm.create()
File "/usr/lib/python2.5/site-packages/libvirt.py", line 262,
in create
if ret == -1: raise libvirtError ('virDomainCreate() failed',
dom=self)
libvirtError: internal error Timed out while reading console startup
output
Same result if I use <source path='/dev/pts/2' />. If I remove the
parallel "hardware" in the virt-manager, the guest starts up OK.
I'm now running
libvirt-0.4.5-2.fc8
virt-manager-0.6.0-1.fc8
on the host.
