Hi, I defined a cdrom to a guest domain as follows. ",hdc:cdrom,r" When the guest domain was created by using xm create command, uname of the cdrom was ''''. Then creating the guest domain succeeded. [2008-06-03 15:23:41 xend.XendDomainInfo 25956] DEBUG (XendDomainInfo:200) XendDomainInfo.create([''vm'', [''name'', ''rhel5.2ga_hvm_lvol1''], <<snip>> [''device'', [''vbd'', [''uname'', ''''], [''dev'', ''hdc:cdrom''], [''mode'', ''r'']]], <<snip>> But, when the guest domain was created by using virsh start command, uname of the cdrom was None. Then creating the guest domain failed. [2008-06-03 15:22:10 xend.XendDomainInfo 25559] DEBUG (XendDomainInfo:200) XendDomainInfo.create([''vm'', [''name'', ''rhel5.2ga_hvm_lvol1''], <<snip>> [''device'', [''vbd'', [''dev'', ''hdc:cdrom''], [''mode'', ''r'']]], <<snip>> This patch fixes to be able to create guest domains by both xm create command and virsh start command. FYI: "if uname is None:" --> "if uname == '''':" --> "if not uname:" till CS#17625 current by this patch Signed-off-by: Masaki Kanno <kanno.masaki@jp.fujitsu.com> Best regards, Kan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
