Hello I''m trying to convert a HVM to PV dom0. The domU is a 10SP2 SLED ( Kernel 2.6.16.60-0.21 i386) and is a SLES11SP2 dom0 (Kernel 3.0.13-0.27-xen 64bit). The truth is that every tutorial I see it differently and I do not know where this error. When I start the domU, pvgrub shows the options but when I select the kenel-xen, returns the error "Boot loader did not return any

Shows that as the MCU increases, the OpenMP extra overhead is amortized and OpenMP becomes as fast as the pthreads implementation. The last chart http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/systime.png Shows that both pthreads and OpenMP overhead decreases as what seems to be a logarithmic function of the MCU size. This was a great experiment, and from what I can conclude, the OpenMP

Hi, I''m using a custom block script in my xen setup and when started, it creates a new device node pointing to some network resources. Now I noticed that the script is called twice for the root block, the first time for pygrub most likely, but is only stopped once ... I don''t mind creating two devices node, but then I need to destroy both ... Is this a known issue ? Cheers,

Yesterday, I had a PV OpenSolaris DomU stop responding. I looked on my xen machine and it was in a paused state. I ended up destroying it and then doing xm create to bring it back up. It won''t boot, and I think PyGrub is hanging. Not sure how to resolve this, there aren''t any errors being presented in xen/xm itself. If I try ''xm create config.conf'' it just

I migrated a CentOS7 VM (the fedrtc.org site) from an XCP environment to a libvirt/KVM environment. This involved using qemu-img to convert the image from VHD to qcow2 and then using virt-install --import to define the VM in libvirt. Three problems occurred during boot: a) on the first boot, the BIOS screen and grub screen don't appear at all, the screen is blank for a couple of seconds and
