I suggest trying the following blacklisting the vhost module so it is not loaded and see if that helps create file /etc/modprobe.d/vhost-blacklist.conf # cat <EOF > /etc/modprobe.d/vhost-blacklist.conf install vhost_net /bin/true EOF reboot the system and then try installing the guest(s) (In reply to comment #1) > I suggest trying the following blacklisting the vhost module so it is not > loaded and see if that helps > > create file /etc/modprobe.d/vhost-blacklist.conf > > # cat <EOF > /etc/modprobe.d/vhost-blacklist.conf > install vhost_net /bin/true > EOF > > reboot the system and then try installing the guest(s) I've tried that but have got the same issue.. Can you please try a few things: - Check the guest logs (kernel, system) and upload them here - Anything obviously wrong with guest networking seen in the logs? - Jes mentions libvirtd starting could be an issue -- can you try a .ks file that removes libvirtd install in the guest? Today I installed on of the systems ibm-hs22-04.lab.bos.redhat.com that was hitting this issue 100% with tree RHEL6.0-20100805.0 the snapshot #10 candidate. I was able to install multiple guests across various versions of RHEL and I did not see the issue.

I'm not sure I follow, is there a problem in snap10 or not? No problem, I was not able to reproduce the problem with snap10. I'll close this issue. Also note that spanning tree is not suitable for virt anyway. |
