I have dom0 with ~1Gb of memory. (About 900Mb as shown in 'xm list' once it is freshly booted.) I start a guest, and that gets decreased as the memory is allocated to domU: Name ID Mem Domain-0 0 735 etch32-builder.my.flat 24 128 After a while I shutdown that guest and I expect the memory to be available to dom0 again - but it never is. I see dom0 left with the reduced ~700Mb. Is that expected? Steve --
