Hi Guys: I met a graphical video crad issue in my pc :Thinkpad x200 In the last months , I use Opensuse 12.2 userspace with kernel 3.7.3, desktop,default , xen flavors are ok. they can enter X window with i915 driver which kms supported. but now I upgrade to 12.3, I found kernel 3.7.10 desktop ,default kernel are ok ,with i915 kms supported. but kernel-xen-3.7.10 l boot ok and can't enter X window. when I add parameter "nomodeset" , can enter X window. wiredly , I use Opensuse 12.3 userspace with kernel-xen-3.7.3 ,when it boots to load i915 module , the screen shows black . of course if I add parameter "nomodeset", can enter X window. why do I need use xen-kernel in PC ? maybe you feel strange , because I want to study xen or kvm virtulization technology. I can't find any useful info in /var/log/messages. -- --------------------------- Suse Linux ,Best ! ---------------------------

[opensuse-virtual] does anybody know a site with good comparison between all the virtual disk image types ?

Hello all, I'm wondering what the pro's and cons of all the volume format types are ? what are the (dis)advantages of any of the following ? raw, bochs, cloop, cow, dmg, iso, qcow, qcow2, qed, vmdk, vpc and what would be the pro's and con's to put a certain volume format on a storage pool type ? Directory pool, Filesystem pool, Logical volume pools, Disk volume pools, ? For example : raw volume format is highly portable, most virtualization solutions support this type nfs is simple to set up as a remote storage pool without huge investments, but performance may not be optimal. iscsi is slightly more complex than nfs but also cheap to set up and when configured properly performs better. lvm partitions are very usefull Does an iscsi lun that is a raw partition on the target server outperform an iscsi lun that is a file on a disk on the target server ? Does anybody know a site that has a good comparison between the ones mentioned above. (or some of them) Regards Rob -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-virtual+owner(a)opensuse.org
