Now I want to install paravirt xen guests. PFA, different screen shots of virt-manager while creating a VM. But the paravirt option is disabled and i am unable to select it. Why is that so?

Fasiha Ashraf

YES

# cd xen-3.4.1
# make uninstall
# rpm -iv xen-3.4.1-4.src.rpm
# cd rpmbuild/SPEC
# rpmbuild -ba ./xen.spec
. . . . . . . .

NO

When xen 3.4.1 and tools are installed via generated rpms proceed with libvirt install
as suggested.

From base kernel environment.

Then install pvops ( or xenified kernel) , create grub entry and reboot.
Currently , 2.6.31.4 (pvops) is running in Dom0 on top of F11 in my environment.
Random xend crashes take place, service xend start to recover.

Boris.

Please help in creating VMs it this case. my virt-manager and virt-install are not working. and I am following this link to create xen DomUs http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/#comment-618

Yes I did, but i have a question about it as well, Since i have compiled xen with this kernel version, Do i need to install it from rpm as well? or just i should skip that step and start installing libvirt?Also tell me should it be done from my dom0 or from the base kernel(nonexen)?

I'd start with running "xm list" and see if your domU is actually
running or not. After that, do something like
I am getting dom0 with running status
[root@Server1-FC11 xendoms]# xm list

to see if there's any process listening on port 5900+. If a domU was
started and it has a vnc GUI, there should be some qemu-dm process
shown there.

Where does loop0 come from? If you're using disk/partition as domU
storage you can simply specify the block device (e.g. /dev/sdb,
/dev/sda4, etc.). If you're using file you can directly use tap:aio.
[root@Server1-FC11 xendoms]# fdisk -l
Disk /dev/sda: 438.4 GB, 438489317376 bytes
255 heads, 63 sectors/track, 53309 cylinders

   Device Boot      Start         End      Blocks   Id System

/dev/sda2              14        2180    17406427+ 82 Linux swap / Solaris

I'm guessing you specified the wrong disk and domU didn't start at all.
I am not using LVM partitions. when i specified one dom disk as /dev/sda i have nothing for next dom. In such situation is it good to use file? like u suggest.
