I just move from CentOS to Fedora 18, and being confused by grub2. the command grub2-mkconfig use default kernel (the one right being use by fedora 18) I try to edit the line: "module /vmlinuz-3.9.6-200.fc18.x86_64 placeholder root=UUID=b7360a1b-cdff-49f3-8da1-f53081a08242 ro rd.md=0 rd.lvm=0 rd.dm=0 rd.luks=0 vconsole.keymap=us rhgb quiet" to "module /vmlinuz-3.9.4 " (this is the kernel that I modify) but get panic when reboot. Should I write a new menuentry manually?

Hi Yechen, Grub2 script checks the Xen options of each Linux kernel''s configuration file under /boot. If no such config, it won''t create the relative entry. You can have a look at the 20_linux_xen script under /etc/grub.d/ to get more details. Best, Meng --- Meng Xu Phd Candidate in Computer and Information Science University of Pennsylvania

I does not find the config as you said. Anyway I write a menuentry manually and now it seems to work. but then when I try to start xend, an error come out as: File "/usr/sbin/xend", line 36, in <module> from xen.xend.server import SrvDaemon File "/usr/lib64/python2.7/site-packages/xen/xend/server/SrvDaemon.py", line 20, in <module> import xen.lowlevel.xc ImportError: libxenctrl.so.4.2: cannot open shared object file: No such file or directory I think my steps to install xen is right. Google says that it''s something wrong with lib64. I never meet this error before in CentOS. Do you have any ideas?

Re: [help] How to install xen with my own kernel on grub2?
Yes! I have fixed this and thank you all the same.
Now the problems come to xend start:
xc: error: Could not obtain handle on privileged command interface (2 = No
such file or directory): Internal error
Traceback (most recent call last):
File "/usr/sbin/xend", line 36, in <module>

xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, ''Internal error'',
''xc_interface_open failed: No
such file or directory'')
google says that /proc/xen should mount to xenfs, while I see no.
I''m still searching the solution :(
why so many errors come out in Fedora?
By the way, what kind of OS do you suggest in Xen development?
I give up CentOS because it''s too hard to find a suitable package when
trying to install software. And the gcc version is also too low.

You need to copy the .config file to /boot and rename it to config-yourKernelVersion. If there is still no grub entry to that kernel, it means your configuration of the kernel does not have "Xen supported as domain 0".

Re: [help] How to install xen with my own kernel on grub2?
Oh yeah I start a domU ! I think the problem is: xend and /etc/init.d/xend this two commands seems different. if I use /etc/init.d/xencommons start and /etc/init.d/xend start, no error comes any more. (however, there should be a "nothing to flush" but I don''t see it. hmm...maybe there is still something wrong here) The old way I create a domU is use "xm create". This way still works, but when I try the new xl command: "xl create", it ask me to stop xend first. We don''t need xend anymore in Xen 4.2?

OTOH, you not only do not need xend, but you actually need to _get_rid_ot_it_ (stopping is enough), if you want to use xl. When choosing, keep in mind that xend is being deprecated. It actually was deprecated already in 4.2 and in 4.3, and won''t probably be even built in 4.4, so move fast to xl/libxl. :-D Actually, having seen another e-mail from you (from yesterday, I think), I guess you figured that out already, but still... :-) Regards, Dario -- <<This happens because I choose it to happen!>> (Raistlin Majere) ----------------------------------------------------------------- Dario Faggioli, Ph.D, http://about.me/dario.faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK) _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
