http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1192 Summary: Using lvsnapshot as the physical disk causes kernel OOPS Product: Xen Version: 3.0.4 Platform: x86-64 OS/Version: Linux-2.6 Status: NEW Severity: major Priority: P2 Component: Guest-OS AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: nick.wilkens@xxxxxxxxxxxxxxxx I created a master installation on a logical volume, masterlv. An lvsnapshot of the masterlv was created, and called xen09lv. When booting the domU of xen09lv the system panics. Below are more details: # uname -r 2.6.18-53.1.14.el5xen # cat /etc/redhat-release CentOS release 5 (Final) # rpm -qa|grep -i xen xen-libs-3.0.3-41.el5 xen-libs-3.0.3-41.el5 kernel-xen-2.6.18-53.1.14.el5 xen-3.0.3-41.el5 # cat /etc/xen/xen09 name = "xen09" uuid = "88f56570-0d6c-48c5-94ec-76172346ec09" maxmem = 128 memory = 128 vcpus = 1 bootloader = "/usr/bin/pygrub" on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" vfb = [ ] disk = [ "phy:/dev/xenvg/xen09lv,xvda,w" ] vif = ['mac=00:16:3e:f3:57:a8 bridge=xenbr0', 'mac=00:16:3e:e3:f2:a2, bridge=xenbr1'] When removing the vif entries from the xen09 config file, the system boots properly. # xm create /etc/xen/xen09 -c Using config file "/etc/xen/xen09".
