Hi all, I understand that currently the standard hibernation mechanisms of operating systems cannot be used with Xen. With Xen, it is possible to use xm save/xm restore which is in its effect quite similar, but I am a bit scared that this might cause problems within the affected OS because after restore, the system clock will show a great leap. This is also true with "native" hibernation, but the OS is aware of this and can react accordingly when it is woken up again. Does anybody know if this really can cause trouble or if - in the PV case - the kernel is patched so to that similar actions are taken as when the OS resumes from hibernation? Recently, I saw a patch on the xen-devel mailinglist that adds S3 support. From my understanding, the potential problems that I have described above would be circumvented if the DomU is put into S3 state and then saved using xm save? Thanks for your patience, dla _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
