Description zhe peng 2013-04-01 08:32:44 UTC 
Description of problem:
when use unix socket in guest , virt-manager can't display the graphic console.

Version-Release number of selected component (if applicable):
virt-manager-0.9.4-5.el7.noarch
libvirt-1.0.3-1.el7.x86_64


How reproducible:
100%

Steps to Reproduce:
# vi /etc/libvirt/qemu.conf
enable vnc_auto_unix_socket = 1

#systemctl restart  libvirtd.service
2:
# virsh start a
Domain a started

# virsh dumpxml a
...
   <input type='mouse' bus='ps2'/>
   <graphics type='vnc' socket='/var/lib/libvirt/qemu/a.vnc'/>
...

use virt-manager to open the guest console.
Actual results:
guest can't show up in virt-manager.


Expected results:
can display the guest

additional: use virt-viewer can open guest w/o error, this worked on RHEL6.4
Comment 2 Christoph Anton Mitterer 2013-05-31 17:33:58 UTC 
Any plans to implement this? Would be quite reasonable, from a security POV.

Any plans to support UNIX sockets with SPICE?
Comment 3 Martin Kletzander 2013-12-02 10:25:31 UTC 
virt-viewer and virt-manager are two separate things.  If it was working in virt-viewer it should be still working, but I don't know about virt-manager having the support.  Do I understand correctly that you want to have the support for vnc with unix sockets?  Or does it mean that you just want to make sure virt-manager adds proper configuration in order to display the guest?

I guess this would be nice to have.  SPICE supports UNIX sockets, but I'm not sure about it's support in qemu and libvirt.
Comment 4 zhe peng 2013-12-03 03:22:15 UTC 
virt-manager support vnc with unix sockets on rhel6.4&rhel6.5
Is this function removed on rhel7?
Comment 5 Martin Kletzander 2013-12-03 10:33:07 UTC 
You're right, sorry for the confusion.  virt-manager supports vnc unix sockets.  What is the error you see in the 'console' tab?

Comment 12 zhengqin 2013-12-11 09:35:32 UTC 
Retest it with virt-manager-0.10.0-8.el7, see the following info just as bug mentioned:


[root@localhost ~]# grep vnc_auto_unix_socket /etc/libvirt/qemu.conf
vnc_auto_unix_socket = 1
[root@localhost ~]# virsh dumpxml rhel6_01 | grep -A5 "input type"
    <input type='mouse' bus='ps2'/>
    <graphics type='vnc' socket='/var/lib/libvirt/qemu/rhel6_01.vnc'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
    <sound model='ich6'>
      <alias name='sound0'/>



virt-manager and virt-viewer could open & see the guest on RHEL7, so, set the status as "VERIFIED"
