I need to add physical cdrom on domU windows and ubuntu. I try with same physical disk on same server, only once domU active for each test. On windows 7 pro 64 bit with gplpv build 308 with cfg ''phy:/dev/scd0,hdc:cdrom,r'' works correctly. On Lucid desktop 64 bit (ubuntu 10.04) (domU pv) with cfg ''phy:/dev/scd0,xvdb:cdrom,r'' does not work correctly. On "computer resources", the cdrom unit is without name of cdrom and is impossible open it. I search on syslog on Lucid domu and find this: ...
