Ok - back to the hvm install, and converting it to a pv domu. Actually, all the heavy lifting has already been done in the hvm install and the pv install. Only three things need to be done for the conversion: 1) As I said, all the /dev/disk/by-id references in menu.lst and fstab have to be changed to /dev/disk/by-uuid. By way of example, look at the end of my /dev/disk tree, and then my menu.lst: /dev/disk/by-id: total 0 drwxr-xr-x 2 root root 220 Dec 3 14:34 ./ drwxr-xr-x 6 root root 120 Dec 3 14:34 ../ lrwxrwxrwx 1 root root 9 Dec 3 14:34 ata-QEMU_DVD-ROM_QM00003 -> ../../sr0 lrwxrwxrwx 1 root root 9 Dec 3 14:34 ata-QEMU_HARDDISK_QM00001 -> ../../sda lrwxrwxrwx 1 root root 10 Dec 3 14:34 ata-QEMU_HARDDISK_QM00001-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Dec 3 14:34 ata-QEMU_HARDDISK_QM00001-part2 -> ../../sda2 lrwxrwxrwx 1 root root 10 Dec 3 14:34 ata-QEMU_HARDDISK_QM00001-part3 -> ../../sda3 lrwxrwxrwx 1 root root 9 Dec 3 14:34 scsi-SATA_QEMU_HARDDISK_QM00001 -> ../../sda lrwxrwxrwx 1 root root 10 Dec 3 14:34 scsi-SATA_QEMU_HARDDISK_QM00001-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Dec 3 14:34 scsi-SATA_QEMU_HARDDISK_QM00001-part2 -> ../../sda2 lrwxrwxrwx 1 root root 10 Dec 3 14:34 scsi-SATA_QEMU_HARDDISK_QM00001-part3 -> ../../sda3 /dev/disk/by-uuid: total 0 drwxr-xr-x 2 root root 100 Dec 3 14:34 ./ drwxr-xr-x 6 root root 120 Dec 3 14:34 ../ lrwxrwxrwx 1 root root 10 Dec 3 14:34 0b95b2ca-ffc6-486c-a11e-8c1086b88d50 - > ../../sda1 lrwxrwxrwx 1 root root 10 Dec 3 14:34 2dcfb1a2-876d-4b36-86a5-d34641331c9e - > ../../sda2 lrwxrwxrwx 1 root root 10 Dec 3 14:34 3ed78b97-5da1-4b3c-a1f0-4a38ba388d78 - > ../../sda3 # Modified by YaST2.

(Yeah, the hvm install only installed the -desktop version of the kernel. I installed the other two with zypper, and upgraded the -desktop kernel. This doesn't change the discussion about /dev/disk/by-uuid.) Eg - see how my ata-QEMU_HARDDISK_QM00001-part2 points to /dev/sda2 (the root filesystem). The UUID 2dcfb1a2-876d-4b36-86a5-d34641331c9e also points to /dev/sda2, so all three are equivalent in the hvm domu. However, the /dev/disk/by-id links completely go away when you boot up with a pv config. (Yeah, I used the pv config I posted, patterned on your pv install config.) Also, the /dev/sdan drives change into /dev/xvdan drives. The preferred standard way of representing the drives then becomes /dev/disk/by-uuid, and I changed that in the -desktop and -xen stanzas. The -desktop stanza boots with the hvm config, and the -xen stanza boots with the pv config. You also need to do the same thing in /etc/fstab. 2) You don't have an X desktop at this point, or an 'xm console ...' login, but you do have a login in the vnc window. Two files need to be edited to get an xm console login. You must edit /etc/inittab, find the line that looks like: #S0:12345:respawn:/sbin/agetty -L 9600 ttyS0 vt102 and add a line above it that looks like: x0:12345:respawn:/sbin/agetty -L 9600 xvc0 xterm Then edit /etc/securetty, and add xvc0 to the end of the list, to allow root to login on the agetty defined above. Then give the command 'telinit q' to tell init to re-read the inittab file, and create the agetty login process for xm console. There is only one drawback to this: When you boot back in with an hvm config, /dev/xvc0 doesn't exist, and you get a lot of annoying error messages in syslog. Just comment out the 'x0' line in inittab, and execute telinit q. I expect this step to be done completely differently in suse 12.1, since the old systemV init system is supposed to be replaced by the systemd daemon, according to the opensuse web site. I've worked with systemd in fedora 15 - it's a bit stiff. ;-( 3) And, finally, this is my xorg.conf: # # This file contains the device names of tty lines (one per line, # without leading /dev/) on which root is allowed to login. # tty1 tty2 tty3 tty4 tty5 tty6 xvc0 root@linux-w421 12/07/11 11:40PM:~ [508] > cat /etc/X11/xorg.conf Section "Monitor" HorizSync 20-220 Identifier "Monitor[0]" VertRefresh 30-320 UseModes "Modes[0]" EndSection Section "Modes" Identifier "Modes[0]" Modeline "1280x1024" 276.24 1280 1384 1528 1776 1024 1025 1028 1111 Modeline "1280x1024" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync Doublescan Modeline "1280x1024_75.00" 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync Interlace Modeline "1280x1024_85.00" 159.50 1280 1376 1512 1744 1024 1027 1034 1078 -hsync +vsync Doublescan Interlace EndSection Section "Device" BoardName "Cirrus Logic GD 5446" Driver "cirrus" Identifier "Device[0]" VendorName "XenSource Inc."

I got the idea from the xorg.conf.install file that the suse install left behind. This ServerLayout tells xorg to try both fbdev and cirrus, and decide which one is best. The end result is exactly the same as the pv install we've been talking about. The resolution is just 800x600, and there is no mouse, despite Xorg.0.log saying the evdev driver found one. Oh, well - at least it's an interesting technical exercise. ;-) I'm out of ideas on the mouse, and the pv resolution. If anyone has any ideas, feel free to chime in. :-) _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
