Gah, I swear I didn't press send there but off it went.

What I was going to say is that if you think there really is enough free
RAM then please can you show us the output of "xl info" and "xl dmesg"
as well as sharing your guest configuration file.

You might also find updating to Xen 4.3.x or Xen 4.4 will help since xl
was much improved in those releases.

Ian.

Here's xl info. I'm not seeing that failure anymore and hence don't have xl dmesg output right after the problem. Updating to higher Xen is not possible because SuSE 11 does not have them yet.
