Description Zack Cerza 2009-10-07 15:02:58 EDT
Description of problem:
Sometimes when I try to start one of my VMs, I get an error dialog saying "Error starting domain: internal error unable to start guest: qemu: could not open serial device 'pty': No child processes" and showing this traceback:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 571, in run_domain
  File "/usr/share/virt-manager/virtManager/domain.py", line 664, in startup
  File "/usr/lib64/python2.6/site-packages/libvirt.py", line 293, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error unable to start guest: qemu: could not open serial device 'pty': No child processes

I'm not sure where to file this, but I'll start with libvirt...

Thanks for the report

Does the /dev/pts in entry in /etc/fstab contain 'gid=5,mode=620' ? See bug #515521
Comment 2 Zack Cerza 2009-10-09 10:16:48 EDT
Turns out that was the problem. Thanks!
