Issue with Xen on CentOS 5.4 x86_64 on Proliant ML115

Hi,

First CentOS rules, the best OS i've ever tried, keep up the good work.

Second, I've recently installed 5.4 x86_64 on an HP Proliant ML115 and I'm having some weird issues, I isnatlled Virtualization group (you groupinstall virtualization), which installed:

Installed:
gnome-applet-vm.x86_64 0:0.1.2-1.el5 kernel-xen.x86_64 0:2.6.18-164.6.1.el5
libvirt.i386 0:0.6.3-20.1.el5_4 libvirt.x86_64 0:0.6.3-20.1.el5_4
virt-manager.x86_64 0:0.6.1-8.el5 virt-viewer.x86_64 0:0.0.2-3.el5
xen.x86_64 0:3.0.3-94.el5_4.2

xend doesn't start, it gives me this error:

ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
Traceback (most recent call last):

xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')

I've search on the web and some blame ruby or something but I really don't understand this, could you point me to some thread or give me some advise on this?.

xm create also reports this:

[root@pbx ~]# xm create win01.cfg
ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
Using config file "/etc/xen/win01.cfg".
VNC= 1

Error: Unable to connect to xend: No such file or directory. Is xend running?


Thanks in advance.

Hi me, how am I, :-D

I solved this problem by simply going into /etc/grub.conf (finally FHS compliancy) :-) and remembered that in computer world "0" is the first number and changed the 1 value there for a 0.

All that after messing my head up, but this epiphany happened. and miraculously I issued a uname -r and noticed that the running kernel wasn't xen-enabled kernel. :-P

Well problem solved and now I've virtualized Debian WinXP and CentOS 5.3 to test my Openvox card because I have an issue with it.

You can close this topic and sorry for the n00b behaviour, it's just that I passed this entire year studying, and my server ran all-alone back there at home for all this months, it had to be Linux.

Thanks!

Happy Holidays. :lol:

It's often those little things that trip us up. ;-)

Pleased to read of your success.

Don't worry about it. You solved your own problem in under 24 hours. As the above posts are your very first two, I'll say "Welcome to the [i]CentOS[/i] fora." :-)

Successfully, I assume?
