* Problems when creating domU on FastModel Cortex-A15 @ 2013-10-14 22:25 XiaoGuang Wang 2013-10-15 14:27 ` XiaoGuang Wang 0 siblings, 1 reply; 7+ messages in thread From: XiaoGuang Wang @ 2013-10-14 22:25 UTC (permalink / raw) To: xen-devel@lists.xensource.com [-- Attachment #1.1: Type: text/plain, Size: 1318 bytes --] Hi all, I tried to create domU on FastModel. But it seems to have some problem when I create the domU. root@dom0:/root# xl create domU-config Parsing config from domU-config Failed to unmap pfn:86cf6 rc:-2 Failed to unmap pfn:87aa5 rc:-2 Failed to unmap pfn:86cf6 rc:-2 Failed to unmap pfn:87aa5 rc:-2 Failed to unmap pfn:86cf4 rc:-2 Failed to unmap pfn:86cf3 rc:-2 Daemon running with PID 85 root@dom0:/root# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 127 1 r----- 6.7 domU 1 100 1 --psc- 0.0 DomU is not actually started. After a while, domU will be disappeared from the list. I made the domU image file by: # cat arch/arm/boot/zImage xenvm-4.2.dtb > /mnt/root/image The domU-config file is as follows: kernel = "/root/image" memory = 100 name = "domU" vcpus = 1 disk = [ 'phy:/dev/loop0,xvda,w' ] And setup loop device like: $ losetup /dev/loop0 /root/domU.img So is there something I have to do with the domU kernel configuration file? I just use the same config file as I used in dom0, from: http://xenbits.xen.org/people/sstabellini/config And if domU is successfully started, where will I see the domU console? (same in dom0 console?) Thanks!

It seems some problems like: libxl: verbose: libxl_create.c:130:libxl__domain_build_info_setdefault: qemu-xen is unavailable, use qemu-xen-traditional instead: No such file or directory The whole log from xl create -vvv is in: http://hi.baidu.com/supernpu/item/79bc6606e802e01ceafe38cf I made the domU kernel image file by: # cat arch/arm/boot/zImage.dom0 xenvm-4.2.dtb > /mnt/root/image And setup loop device like (the FS image follows the same instructions used when creating dom0): $ losetup /dev/loop0 /root/domU.img So I'm not sure how can I see the domU console?

Lets stick with xen-unstable (aka 4.4-pre) latest for now rather than jumping around the versions. Kernel 3.11 or 3.9 should be fine, I'd be inclined to go for the later one. > There is no "Failed to unmap pfn:86cf6 rc:-2" error. But I still > cannot create domU. It seems some problems like: > libxl: verbose: > libxl_create.c:130:libxl__domain_build_info_setdefault: qemu-xen is > unavailable, use qemu-xen-traditional instead: No such file or > directory This is an x86ism which has leaked into ARM, there should be no qemu at all. I think this ought to be harmless. > The whole log from xl create -vvv is in: > http://hi.baidu.com/supernpu/item/79bc6606e802e01ceafe38cf FYI it is a lot easier for everyone if you just paste the whole thing into email... I see you have used "xl -vvv create <cfg> -c". Although I think it isn't hurting for now please drop the "-c" to avoid confusion at this stage. If things were working it would autoconnect the console, but it would have to be before <cfg> to work, I think. I can't see anything untoward in your log, it seems to think it has started the domain OK but by the time you run xl list it has gone. There should be other logs under /var/log/xen/*domU* -- please can you post them, they may give a clue. You could also try "xl -vvv create -F <cfg>" which will cause xl to stay in the foreground and perhaps let you see more logs. > So I'm not sure how can I see the domU console? xl list shows that the domain isn't even running, so you can't. Once it is the "xl console <domain>" will work. So would "xl create -c <cfg>" (but as mentioned above not "xl create <cfg> -c", I don't think).

This log shows something like: Domain 3 has shut down, reason code 3 0x3 Action for shutdown reason code 3 is destroy So I search for your previous suggestion on this problem, and enable the guest (domU) console log.
