[libvirt] kqemu

Hi I could not get an answer from the users list . Maybe here someone can give some advice . we have a Linux 64 bit system with qemu 0.9.1-10 ( uname -a = 2.6.26-2-amd64) installed . kvm is included and loaded to memory . Still when we create a VM we sometimes get the following error message: libvir: QEMU error : internal error unable to start guest: You do not have enough space in '/dev/shm' for the 499 MB of QEMU virtual RAM. To have more space available provided you have enough RAM and swap, do as root: mount -o remount,size=515m /dev/shm Or disable the accelerator module with -no-kqemu After we do the mount (as advised) we can create the VM . Does the error mean that kvm is not active ? It seems that kqemu is an old way to do the duties of kvm e.g supply memory to VMs via /dev/shm . Is there a way to avoid that error ? I guess the -no-kqemu should be to qemu but we do not have control over the invokation of qemu by libvirt. thanks Zvi Dubitzky Email:dubi@il.ibm.com
