Fedora xen - Nov 2006 - RE: virt-manager gives "The console is currently unavailable" in FC6

I had a typo in my previous message.

I see no errors in xend.log and xend-debug.log.

But I do have qemu*log messages. For my last problem, I only see the
following
Domid: 2
Shared page at pfn:ffff, mfn:34cd5
Buffered io page at pfn:fffd, mfn:34cd7

This basically means that virt-manager was unable to successfully
connect
to the VNC server which exports the guest framebuffer / console. Since
you say this is with fully virt, it probably means that the qemu-dm
process
failed to startup correctly - since VNC itself rarely fails I imagine
some
other bit of the guest config broke - network / disk setup being most
likely

What are the errors you see - they may well help diagnose the problem
you are encountering ? Also check for /var/log/xen/qemu-dm*.log for
info about the fully-virt device model startup

Ok, that''s good - can you see if there is a qemu-dm process running,
eg

  ps -auxfww | grep qemu-dm

Looks reasonable. Can you see if there is a ''<graphics>''
block
in the XML  when you run

  ''virsh dumpxml  <domain name>''  

For the domain that you failed to get a console on. Also make sure that
in the /etc/xen/<domain name> there is a ''vnc=1'' config
option. Finally,
take a look at /root/.virt-manager/virt-manager.log to see if there''s
any errors reported.

Hello,

Actually, I have exactly the same problem with FC6 for some days now.
Concerning Daniel''s questions (for me) :

- qemu process : ok
- virsh dump : ok but why port=-1 ?
<graphics type=''vnc'' port=''-1''/>
- virt-manager log :
Unable to activate console socket.gaierror (-2, ''Nom ou service
inconnu'')
(detail is given below).

What strange is, it is that everything worked well at beginning.
I have not made system modifications or so. It''s the third time that I
have
to install FC6.

It would be really great if you have an idea about what is happening.
Thanks for your help

Hmm, that''s very bad - that should never happen ! I''ll have to
investigate
just what scenario could cause that to happen.

Could you also let me know what kernel-xen, virt-manager, libvirt and xen
RPM version you have. And whether its 32 or 64 bit ?

Dan.
