i was having problems with altaro backup with one of virtual servers. it was suggested the host server had the same disk id as the virtual server (which it had) and was asked to change the diskid on the vm.
i did this using the instructions on http://www.digitalhijinx.com/forums/viewtopic.php?p=14508
the disk id changed successfully..
however the virtual server will now not boot... it asks me to enter my bood cd and repair... i am reluctant to do this yet... does anyone have any suggestions?
