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

[opensuse-virtual] xendomains starts domains although xenstore is not started on opensuse 12.3

Hi, I've installed opensuse 12.3 as dom0 and after a reboot my first three domUs don't start. In the logfile /var/log/messages I see the following messages, which let me assume, that xendomains is started (16:34:27) even xenstore has finished starting (16:34:30). So what can I do to let xendomains start after xenstore has finished starting ? For a test I added a sleep 5 at the beginning of xendomains script and now all my domUs will be started at boot time. Here the log: --snip-- 2013-03-14T16:34:27.481310+01:00 xen xendomains[737]: Starting auto Xen domains 2013-03-14T16:34:27.501932+01:00 xen kernel: [ 13.677948] pciback 0000:02:00.0: seizing device 2013-03-14T16:34:27.541912+01:00 xen kernel: [ 13.716108] pciback: backend is vpci 2013-03-14T16:34:27.549890+01:00 xen xendomains[737]: 01gateway: libxl: error: libxl.c:87:libxl_ctx_alloc: Is xenstore daemon running? 2013-03-14T16:34:27.551241+01:00 xen xendomains[737]: failed to stat /var/run/xenstored.pid: No such file or directory 2013-03-14T16:34:27.551494+01:00 xen xendomains[737]: cannot init xl context 2013-03-14T16:34:27.569904+01:00 xen kernel: [ 13.746993] blktap_device_init: blktap device major 252 2013-03-14T16:34:27.569938+01:00 xen kernel: [ 13.747007] blktap_ring_init: blktap ring major: 251 2013-03-14T16:34:27.581928+01:00 xen xendomains[737]: libxl: error: libxl.c:87:libxl_ctx_alloc: Is xenstore daemon running? 2013-03-14T16:34:27.584768+01:00 xen xendomains[737]: failed to stat /var/run/xenstored.pid: No such file or directory 2013-03-14T16:34:27.585035+01:00 xen xendomains[737]: cannot init xl context 2013-03-14T16:34:27.588725+01:00 xen xendomains[737]: ..failed 2013-03-14T16:34:27.621915+01:00 xen kernel: [ 13.797019] nbd: registered device at major 43 2013-03-14T16:34:27.665693+01:00 xen xendomains[737]: 02appserver: libxl: error: libxl.c:87:libxl_ctx_alloc: Is xenstore daemon running? 2013-03-14T16:34:27.665752+01:00 xen xendomains[737]: failed to stat /var/run/xenstored.pid: No such file or directory 2013-03-14T16:34:27.665771+01:00 xen xendomains[737]: cannot init xl context 2013-03-14T16:34:27.703149+01:00 xen xendomains[737]: libxl: error: libxl.c:87:libxl_ctx_alloc: Is xenstore daemon running? 2013-03-14T16:34:27.704894+01:00 xen xendomains[737]: failed to stat /var/run/xenstored.pid: No such file or directory 2013-03-14T16:34:27.705269+01:00 xen xendomains[737]: cannot init xl context 2013-03-14T16:34:27.708517+01:00 xen xendomains[737]: ..failed 2013-03-14T16:34:27.718325+01:00 xen xenstored: Checking store ... 2013-03-14T16:34:27.815521+01:00 xen xenstored: Checking store complete. 2013-03-14T16:34:27.822758+01:00 xen xencommons[736]: Starting C xenstored... 2013-03-14T16:34:27.824299+01:00 xen xencommons[736]: Setting domain 0 name... 2013-03-14T16:34:27.841961+01:00 xen kernel: [ 14.019412] Unable to read sysrq code in control/sysrq 2013-03-14T16:34:27.843873+01:00 xen xencommons[736]: Starting xenconsoled... 2013-03-14T16:34:27.867333+01:00 xen xencommons[736]: Starting QEMU as disk backend for dom0 2013-03-14T16:34:29.706697+01:00 xen network[697]: Setting up network interfaces: 2013-03-14T16:34:30.251881+01:00 xen network[697]: lo 2013-03-14T16:34:30.257606+01:00 xen ifup[1338]: lo 2013-03-14T16:34:30.392449+01:00 xen ifup[1338]: lo 2013-03-14T16:34:30.405255+01:00 xen ifup[1338]: IP address: 127.0.0.1/8 2013-03-14T16:34:30.407941+01:00 xen network[697]: lo IP address: 127.0.0.1/8 2013-03-14T16:34:30.415491+01:00 xen ifup[1338]: 2013-03-14T16:34:30.583589+01:00 xen systemd[1]: Started LSB: Start/stop xenstored and xenconsoled. --snip-- -- Gruß Dieter -- I do not get viruses because I do not use MS software.
