Hello. I have set up Xen 3.0.2 and 3.0.3 using the howto "http://www.howtoforge.com/debian_sarge_xen_3.0.3". The Dom0-system and the DomU-system are running on Debian 3.1. So far it works, except for some (minor) problems. First: If I use the compiled xen-kernel (the one created with "make world" and "make install"), the host system works fine, no problems at all. If I use the xen0-kernel, created by using "make linux-2.6-xen0-config CONFIGMODE=menuconfig KERNELS="linux-2.6-xen0"" (step 4.2 in the above mentioned howto), i get some ugly load-problems using the host system. I.e. copying a file from /dev/hdc1 to /dev/hda4 takes forever, the kjournald takes 99,9% of cpu time (the same happens if I use ftp to copy anything to the host machine). So working with the xen0-kernel is not possible. Second: I ran into some problems with my virtual machines. They start up ok and run without problems as long as I don't do anything that requires a large amount of memory. The problem: the VM's don't use swap memory. The config file looks like this: Code: name="vm01" kernel="/boot/vmlinuz-184.108.40.206-xenU" root="/dev/sda1" memory=128 disk=['file:/mnt/storage/vserver/vm01.img,sda1,w','file:/mnt/storage/vserver/vm01-swap.img,sda2,w'] # network #vif = ['mac=00:00:00:00:00:01' ,'bridge=xenintbr'] vif = ['ip=10.80.0.2'] dhcp ="off" ip="10.80.0.2" netmask="255.0.0.0" gateway="10.80.0.254" hostname="vm01" extra="3" So the VM should be able to use swap. Output of "cat /proc/partitions" inside the VM: major minor #blocks name 8 1 1024000 sda1 8 2 512000 sda2 I honestly don't understand why the virtual machines don't use swap at all. I recently purged hotplug, replacing it with udev, but that didn't change a thing (even compiled a new kernel). I would appreciate any help. Regards, Merc ps: I searched the xen-source-forum but didn't find a solution to the above mentioned problems. The swap-problem was mentioned there, but no solution (it was said using udev instead of hotplug would solve the problem, but it didn't, at least not for me).
