Re: [Xen-users] Does xen on debian squeeze work at all?



Hello Shane!

Thank you for your suggestion, but, in effects xend is NOT running: that is the problem.

If you take the burden to follow the thread backwards, you will find my previous posts that show all my findings.

In a few words: xend does not start because a file is missing or misplaced, but I don't know which one.

Ciao,
Ric

Ric,
If you run the command :
ps -A | grep xend

do you see the process with a pid?  if you do it is running if not  you will have to see what is preventing it from running in the log files.  

Sincerely
Shane

Hi Linus!

First of all, thanks a lot for taking the time to write down your suggestion...

Well I am pretty sure that the hypervisor is running, because I see (flushing rapidly) a certain number of "(XEN) blabla" lines at boot time.

Next, I checked the /sys/xen/capabilities file, which contains the string "control-d", and, as a xen-user (Eva) said earlier, it means that the hypervisor is in control.

My (un)educated guess is that some (virtual) disk driver is missing or misplaced...

Ciao,
Ric

I peeped into /var/log/xen/xend-debug.log and found:

Xend started at Thu Jan 19 11:29:27 2012.
cat: /sys/bus/scsi/devices/host0/vendor: No such file or directory
cat: /sys/bus/scsi/devices/host0/model: No such file or directory
[..]
Exception starting xend: (2, 'No such file or directory')

This sounds "good": where are my disks? I have got an ATA and an SATA
disk, doesn't xend find them?

Still looks like your systems boots directly into Linux w/o starting
the Xen hypervisor first.
Try to manually select the Xen hypervisor in the grub boot menu when
your system starts.

Should be called something like "Debian GNU/Linux, with Linux
2.6.32-[..] and XEN 4.0-amd64'.
