Hi all,
I have one problem, who can help me resolve this problem?
I have installed xen in centos(GUI mode), at first I can use "xm
new test" correctly. However, after that I reinstall my centos in text
mode and reinstall xen in my new centos(no GUI), when I type the
command "xm new test.cfg", one error print as belowes.
Unexpected error: exceptions.ImportError
Please report to xen-devel@lists.xensource.com
Traceback (most recent call last):

I have no idea, who can tell me why and how to resolve that. Thanks a lot.
Best Wishes!

Compile from xen.org''s source? Installing centos package should install the dependencies as well, but when installing from source it''s possible that you miss one of the dependencies.> when I type the > command "xm new test.cfg", one error print as belowes. > > Unexpected error: exceptions.ImportError > > Please report to xen-devel@lists.xensource.com > Traceback (most recent call last): > File "/usr/sbin/xm", line 7, in ? > main.main(sys.argv) > File "usr/lib/python2.4/site-packages/xen/xm/main.py", line 2997, in main > File "usr/lib/python2.4/site-packages/xen/xm/main.py", line 3021, in _run_cmd > File "<string>", line 1, in <lambda> > File "usr/lib/python2.4/site-packages/xen/xm/main.py", line 1366, in > xm_importcommand > File "/usr/lib/python2.4/new.py", line 26, in ? > > File "usr/lib/python2.4/site-packages/xen/xm/xenapi_create.py", line 23, in ? > ImportError: No module named xmlproc > > I have no idea, who can tell me why and how to resolve that. Thanks a lot.Looks like one of the necessary python module (PyXML) was not found.

Hi all, I thought my cpu soft lockup issue were behind me with the addition of the sched-credit stuff. However I''m still experiencing the lockup issues when an domU does anything cpu intensive. A large tar will completely hang it. This has lead me to try to upgrade/change the kernels on my servers. I started by downloading the source from xen.org and compiling on my Ubuntu Xen dev server. This went surprisingly well. However when I put the new kernel in grub it will not boot as it can''t find the root. I set root=/dev/cciss/c0p01 which should have worked. I tried by UUID, root=UUID=9da5323b-e47c-4367-bed0-2d2b53ba5a45 and still no joy. After six hours of every combo possible I gave up and threw a new set of drives in the machine and installed Centos 5.2. The Centos install went fine and I installed the stock xen. I moved over a test domU and tried to add it with xm new. Of course the xen from the Centos distro is like 3.0 and doesn''t even have the xm new option. So I try to start with xm create and I get the following error: ACMError: Policy file ''/etc/xen/acm-security/policies/-security_policy.xml'' not found. I did a few searches and see some work arounds/fixes but decide I''ll try to build the latest as I did on Ubuntu. I''ve now done 7 builds only to have it fail every time an hour into it with some dependency that should have been installed. I did a yum groupinstall ''Development Tools'' and verified that I had all the dependencies installed as stated in the README. It still amazes me that there is stuff missing (this last time it was makeinfo?). It''s running yet again but I don''t have high hopes that it''s going to complete without additional problems. I''ve now spent over two full days trying to get some stability with no luck. Is there any somewhat current (at least 3.3) yet stable 32 bit version of Xen out there with a simple installer? I know if I had 64 bit machines I could have easily used http://www.gitco.de/repo/ to update Centos. However new hardware right now is not an option. I''m open to any distro that is going to make this easier. At this point my frustration level is so high that I''m actually considering moving everything back to VMWare 3.5! Any ideas before I pull out the little hair remaining on my head?

Hi again, Of course after ranting, the last build on Centos finished. I added to grub and rebooted. Just like with Ubuntu I can''t get the system to find the drive. I have tried root=/dev/cciss/c0p01 and root=/dev/VolGroup00/LogVol00. I checked and /lib/modules/2.6.18.8-xen/kernel/drivers/block/ contains cciss.ko. Is the problem not the HP RAID but maybe because of LVM? Any ideas as to how to troubleshoot this? FYI the server is a HP DL380 G3 with the HP Smart Array 5i controller.

I have a similar problem. I am running Debian Lenny and the Xen kernel (2.6.18.8) is unable to recognize my hard drive (/root/sda1). What actually happens is that it drops me to the BusyBox shell.I have tried switching to IDE mode in BIOS but it didn''t help. The problem exists with both the stable kernel version for Xen 3.4.2 and the unstable version for Xen 4.0.0. However, it works with 2.6.26-2-xen-686 from Debian repositories but this kernel version doesn''t support Xen 4... and this is what I actually need. Hope someone knows how to help us!

You can try official Jeremy Fitzhardinge pvops kernel as well :-
# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
linux-2.6-xen
# cd linux-2.6-xen
Enabling Xen Dom0 support and static cmd line
# make menuconfig
having to two grub entries for xenified ans pvops kernel.
I do believe that required backports will be done to Xen 3.4.3
when APIC Rework (and etc) making pvops kernel usable only by Xen 4.0
will be committed into the most recent pvops kernel in next few months
View JF''s message :-
http://old.nabble.com/xen.git-plans-tt26894238.html
In meantime both kernels work for me pretty stable on Ubuntu 9.10 Server..
However, xenified kernel 2.6.31.8 shows up better performance for OpenSolaris PV
guests
I also believe that in meantime it is possible to pass parameters to kernel
via grub2 kernel like :-

*** This bug is a duplicate of bug 216176 ***
https://bugs.launchpad.net/bugs/216176
This SOLVED the problem for me:
For explanation: Please see this "bug" which is actual a "bug
fix" in
grub2 making it require a second argument in the multiboot command where
grub-legacy did not. http://www.mail-archive.com/grub-
devel@gnu.org/msg11801.html
This explains the issue with grub2 and multiboot lines seemingly
ignoring the kernel root= command line parameter (xen in particular).
A corrected grub.cfg menuentry section from above would read:
menuentry "Xen 3.5 / Ubuntu, kernel 2.6.31.4-1-xen" {
recordfail=1
if [ -n ${have_grubenv} ]; then save_env recordfail; fi
set quiet=1
insmod ext2
set root=(hd0,1)
search --no-floppy --fs-uuid --set 41102bda-f368-45b9-8066-fa971325b228
multiboot /xen-3.5-unstable.gz /xen-3.5-unstable.gz
module /vmlinuz-2.6.31.4-1-xen root=/dev/mapper/vg0-root ro quiet splash
module /initrd.img-2.6.31.4-1-xen
}
As you can see, the multiboot argument /xen-3.5-unstable.gz is
duplicated (repeated twice) as it should be to provide a multiboot
kernel filename and name. This is a new requirement for grub2 (grub-
pc).

I added to grub and rebooted.Since you''re using Centos, the easiest way to start would be install xen and kernel-xen from Centos, and then upgrade xen (and related RPMS) from http://www.gitco.de/repo/ to get a working xen 3.4.2, but still using Centos'' kernel-xen. It should support most of newer xen features, like "xm new" and "vcpu_avail" (on domU config file) However you DID say you''re running 32bit, so you could either: - rebuild gitco''s SRPM for 32bit (some changes needed to SPEC file) - build xen manually, and ONLY use the hypervisor and userland tools, while still using Centos kernel-xen. Your grub section shoud then look similar to this title Red Hat Enterprise Linux Server (2.6.18-164.2.1.el5xen) root (hd0,0) kernel /xen.gz-3.4.1 module /vmlinuz-2.6.18-164.2.1.el5xen ro root=/dev/rootvg/rootlv module /initrd-2.6.18-164.2.1.el5xen.img -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
