As reported in bug 523148 comment 3 (https://bugs.launchpad.net/bugs/523148/comments/3) , there is a bug with current lucid preventing 'virsh console' from working.
Copied from the link above:
| # virsh console guest1
| Connected to domain guest1
| Escape character is ^]
| 14:25:40.056: error : vshRunConsole:77 : unable to open tty /dev/pts/3 : No such file or directory
|
| When I dump the configuration of my VM, something is wrong with the path "/dev/pts/3" (there is a carriage return after the path).
|
| # virsh dumpxml guest1
| <domain type='kvm' id='2'>
| <name>guest1</name>
| ...
| <serial type='pty'>
| '/> <source path='/dev/pts/3
| <target port='0'/>
| </serial>
| '> <console type='pty' tty='/dev/pts/3
| '/> <source path='/dev/pts/3
| <target port='0'/>
| </console>
| ...
| </domain>
The 'path' entries are added by libvirt after launching a domain with:
<serial type="pty">
<target port="1"/>
</serial>
<console type='pty'>
<target port='1'/>
</console>
</devices>
The solution is found at http://libvirt.org/git/?p=libvirt.git;a=commit;h=c0a9b6a5338e54b64a4a28415ffbdb6bcc2b38c5
Note, this is not a dupe of bug 523148. In lucid you wont get far enough to see that bug. Without the change console in 'virsh' is completely broken.
