I didn't find any posts about it - at least, not after the 3.1 release date (maybe it was discussed earlier). Also, there's one more feature which doesn't work for me: - Preliminary save/restore/migrate support for HVM (e.g. Windows) VMs; What does "preliminary" mean here? I tried saving/restoring HVM domains, but it just doesn't work. When I try to do /etc/init.d/xendomains stop, it does something for a long time, and then, my SSH session is just disconnected. When I log in again, xend doesn't work anymore: # xm list Error: Unable to connect to xend: Connection refused. Is xend running? When I start xend again, and then start xendomains, there is my domain in a weird state: # xm list Name ID Mem VCPUs State Time(s) Domain-0 0 256 2 r----- 134.9 migrating-w2k3-001 2 1759 1 ---s-- 64.4 Similar happens when I try to save the domain manually: # xm save w2k3-001 /srv/check-2k And Xen server restarted. (...) I inspected the logs, and it was the OOM-killer. Should it ever happen when saving a guest domain? Xen host has 256 MB RAM for dom0 (3 GB total), Xen guest 1.7 GB. -- Tomasz Chmielewski http://wpkg.org
