Ok, wile waiting for the fix show up in the public mercurial tree I've workarounded the issue with a wrapper script which redirects xc_save stderr to a file. There I get this: FNI 21 : [10000003,768] pte=25fae063, mfn=00025fae, pfn=00001b00 [mfn]=deadbeef FNI 21 : [10000003,769] pte=25faf063, mfn=00025faf, pfn=00001b01 [mfn]=deadbeef FNI 21 : [10000003,770] pte=25fb0063, mfn=00025fb0, pfn=00001b02 [mfn]=deadbeef [ ... many more of these ... ] In the source code there where message is printed I find a comment saying "/* I don't think this should ever happen */". Hmm. It does. And probably it is a problem. "xm save" works now, but I can't restore the domain: master-xen root /tmp# xm restore /vm/ttylinux/suspend.img Error: Could not read store/console MFN Ideas anyone? This is a ttylinux instance running out of a ramdisk. Gerd
