I thought there was supposed to be an ability for domU’s to be put into a hibernated state (E.g. current running tasks and memory) when dom0 is shutdown or rebooted. When

I look in my /etc/default/xendomains file, I have the variable’s “XENDOMAINS_SAVE=/var/lib/xen/save” and “XENDOMAINS_RESTORE=true”. However, when I reboot, I always have

to restart my domains manually and their state was not saved.


My current configuration is as follows: Xen 4.2.1, dom0: Debian 7.0, domU:Debian 7.0, dom0 kernel 3.2.0-4


Any idea on what I need to do to get this working properly?





Just to make sure we've covered the basics, have you also created the configuration files for the VMs that you want to auto save/restore in /etc/xen/auto ?




Will placing a symlink to my .cfg file in that directory save the state of the domU or just have it automatically start when the computer is rebooted?
