I built gentoo-sources-3.2.1-r2 (my other machine is using this without issue) and gentoo-sources-3.4.11 (users list is reporting successes with 3.4 so I decided to test) and tried them both, no change from gentoo-sources-3.6.1 and gentoo-sources-3.6.2.

Xen itself is on 4.1.2, which is also the same as the other computer that is working

 

Could this issue somehow be hardware related?

The motherboard is a S5000PSL

I have 2 Intel Xeon L5410’s installed. Below is the cpuinfo:

I have 8GB of ram. And here is my output from xl list:

When I attempt to start  the VM I get:

starlake ~ # xl -vvvv create /etc/xen/server2008.cfg

Parsing config file /etc/xen/server2008.cfg

libxl: error: libxl_create.c:317:libxl__domain_make domain creation fail

The first time I try to start it, it sits on Parsing config file /etc/xen/server2008.cfg for several seconds before outputting the rest.

After that first time, it instantly comes back with the error.

So apparently Jacek sent this to me personally and I didn’t notice.

 

Anyone have ideas?

I have upgraded the kernel to 3.6.2-gentoo, it got unmasked, with no change.

I’m going to try and find a 3.2.1-gentoo-r2 and move back to that as a test later.

Both machines are Funtoo Linux.

Both machines are running Xen 4.1.2

The old machine is running 3.2.1-gentoo-r2

The new machine is running 3.6.1-gentoo

 

Which logs? The new machine has yet to have anything appear in the /var/log/xen folder yet.

Revdep-rebuild didn’t find anything wrong with my dynamic linking.

What version of den are you running on what version of os and did you look in logs for missing libraries

I’m upgrading and trying to move a VM to a new machine. I copied the config file from the original machine and copied the image file as well.

Other than the error on the console, I am not getting any logs to try and confirm what is wrong.

 

This is the error.
