Hi,
I'm having another problem with my KVM setup, using Fedora 18. For debugging
pruposes, I added two serial ports to my virtual machines, like this :
<serial type="pty">
<target port="1 (or 2)" />
</serial>
On the Linux guest, everything works fine. On the Windows 7 guest, I only get
one of the two ports. The one showing up works well, but I don't understand
why the second one doesn't show up. libvirt reports the creation of the char
devices on the logs, without any error.
I just tried on F19 and it works for me with a windows 7 VM. The device XML is:
<serial type='pty'>
<target port='0'/>
</serial>
<serial type='pty'>
<target port='1'/>
</serial>
<console type='pty'>
<target type='serial' port='0'/>
</console>
The relevant command line bits in /var/log/libvirt/qemu/win7.log were:
-chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0
-chardev pty,id=charserial1 -device isa-serial,chardev=charserial1,id=serial1
No virtio-win drivers or anything FWIW.
If that roughly matches what you are seeing, it's likely an F18 qemu bug. You
can file it against F18 but my main recommendation would be to update to F19
since it will be more actively supported going forward.
