[GRASS-dev] [SAC] OSGeo "tracsvn" VM down

FYI - work in progress but it probably depends on the sysadmins who
host the OSGeo infrastructure.

Anyone with Gentoo and KVM is welcome to help Martin Spott.

Hi,
I wonder how to restart the "tracsvn.osgeo.osuosl.org" VM on the
"osgeo3" from command line.

We found out that the VM is down but the Ganeti Web Manager told me it
was running. But apparently it was unavailable (no HTTP, no SSH, no
ping).
I called an "immediate shutdown" of the VM in order to get into a
consistent state. After calling a subsequent "start" in the Ganetí Web
Manager I was told:

"Error checking bridges on destination node 'osgeo3.osuosl.bak': Error
60: SSL certificate problem: certificate has expired"

I do have access to the physical "osgeo3" machine but I have no idea on
how to start KVM guests on Gentoo (many KVM support pages recommend
"virsh", but there's no such command on "osgeo3"). I found a nice Wiki
page:

  http://www.linux-kvm.org/page/KvmOnGentoo

.... which says:

"there are no standard Gentoo way to do this, you will need 3rd party
scripts/front-ends"

I tried to put the Ganeti utilities into well-defined state (as a test
balloon for rebooting the entire machine) by restarting
"/etc/init.d/ganeti" but ended up in:

" * Starting ganeti-masterd ...
  * exit code 1 [ !! ]"

Please help me start this VM, I don't want to reboot the entire host
just to start a single VM.

Thanks,
        Martin.

@Martin,

was there recently a kernel update to the (Gentoo-)host? If yes, from my
minorest experience, it's not uncommon to have to ensure that the newer kernel
has been configured with support for specific modules (obviously,
related to KVM) or it is necesary to re-compile some modules (again,
obviously) related to KVM.
