Hi guys.
DomU config
disk = [
''phy:/dev/xen00/debian5-base,sda1,w'',
''phy:/dev/xen00/debian5-swap,sda2,w'',
]
-----------------------
mkswap /dev/xen00/debian5-swap
But in domU in booting:
Activating swap...failed.
What wrong?

Or perhaps you use newer kernels, which silently convert the disk to xvda2? -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi, I think about swapless domUs - in conjunction with Xen+drbd installation. Swapless DomU - could be easier administrated but, maybe higher CPU requirements don''t balance advantages. Are there any rules or best practice about swapless VMs? regards Longina -- Longina Przybyszewska, system programmer IT@Naturvidenskab IMADA, Department of Mathematics and Computer Science University of Southern Denmark, Odense Campusvej 55,DK-5230 Odense M, Denmark tel: +45 6550 2359 - http://www.imada.sdu.dk email: longina@imada.sdu.dk -- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I don''t think you can mount a swapfile as a physical disk like that. You''ll need to create a partition structure in the file, and set the partition as swap.>From Dom0:# losetup -f /dev/xen00/debian5-swap # fdisk /dev/loop0 (or whatever loop device it creates; check with losetup -a) (create your swap partition) # kpartx -av /dev/loop0 # mkswap /dev/mapper/loop0p1 # kpartx -d /dev/loop0 # losetup -d /dev/loop0 Or you can do a lot of this work natively from the DomU OS.
