You don't need to restart actually. Just run xm vcpu-set 0 1 xm vcpu-pin 0 0 0 This will set dom0 to use only 1 CPU, CPU0. To have other domU NOT use that CPU, you need to add this option on every domU config cpus="^0" If you don't want to restart domUs, then simply look for the ones that's using CPU0 and relocate it xm vcpu-list xm vcpu-pin ... Note that this doesn't directly related to your problem though, but IMHO it's a best-practice. > Can i do the xend restart without any influence on the domUs? You should be. But again, it's not necessary in this scenario. > mmh, in the top below I can see that much pyhton stuff. > My xen domU check uses "xm list", can that be a problem? > This check gets exectuted for each domU, so i can happen that it runs > as much at one as there are domUs. Probably. You should limit it to run only one at a time (I don't know how though). > 6553 ? S 18:37 /usr/bin/python /usr/sbin/yum-updatesd You MIGHT want to try disabling this as well. service yum-updatesd stop chkconfig yum-updatesd off It uses python, and not very useful anyway if you don't use a GUI (gnome,kde) on that server. On a side note, you might want to add some memory monitoring on that server. That should give you some info on when, how, and why you can get out-of-memory.
