libvirt: virsh -c qemu+ssh://host.example.com/session connects to 'system', not session

[Jamie Strandboge]

On the libvirt host that has virtual machines:

$ virsh -c qemu:///session list --all
 Id Name State
------------------------------

But logging in remotely yields:
$ virsh -c qemu+ssh://host.example.com/session list --all
 Id Name State
----------------------------------
  - Ubuntu 6.06 (Dapper) shut off
  - Ubuntu 6.10 (Edgy) shut off
  - Ubuntu 7.04 (Feisty) shut off
  - Ubuntu 7.10 (Gutsy) shut off
  - Ubuntu 8.04 (Hardy) shut off

What is happening is that qemu+ssh://host.example.com/session is listing the machines in qemu+ssh://host.example.com/system instead. This is both unexpected and wrong, because machines actually in 'session' are not accessible.

Marking confirmed, as it is easily reproducible, and I have done it in different installations. This also is still a problem on Jaunty.

Confirmed in Lucid.

I run virsh -c qemu:///session list --all and virsh -c qemu:///system list --all

when run virsh -c qemu:///session list , it run a temp libvirtd --timeout 30 by non-root model

virsh -c qemu:///system list --all ,it access root model libvirtd

when run virsh -c qemu://127.0.0.1/session list --all

it run a ssh like this:

ssh 127.0.0.1 sh -c 'nc -q 2>&1 | grep -q "requires an argument";if [ $? -eq 0 ] ; then CMD="nc -q 0 -U /var/run/libvirt/libvirt-sock";else CMD="nc -U /var/run/libvirt/libvirt-sock";fi;eval "$CMD";'

so ,does it use a root model libvirtd ??

is here a mistake ?

[Serge Hallyn (serge-hallyn)]

What do you mean by 'a root model libvirtd'?

If you change it to 'virsh -c qemu://127.0.0.1/system -list --all', does it become 'nc -q 0 -U /var/run/libvirt/libvirt-sock-ro' ?

[Serge Hallyn (serge-hallyn)]

Interestingly,

virsh -c qemu+ssh://localhost/system list
versus
virsh -c qemu+ssh://localhost/session list

works correctly. But using just 'qemu:///session list' does inded show system entries.

[Serge Hallyn (serge-hallyn)]

No, I was misreading the results.
