Re: [Xen-users] Best way to get Xen into Ubuntu Natty/64bit
I settled on OpenSUSE since they seemed to be the most commited to having Dom0 support. RHEL 6 doesn't run as a Dom0 (Xen Host), you have to RHEL 5, I think Fedora Core 16 is trying to get this up to date though.
I'm not really a Debian guy so I can't comment there, but I had no problems with OpenSuSE, and I had Windows 7 Pro running on it fine, using LVM, within a day, so I can definitely recommend that. It's got KDE 4 too, which I'm giving a chance even though I'm generally a Gnome guy.
The only hitch I hit I've had is my Dom0 can't currently connect to the windows box using bridged mode unless I'm root, but I need to try the routing scripts to see if that fixes it. The rest of the machines on the network can RDP to the hosted Windows machine fine, but I haven't looked at that in the last week.
Best of Luck

Hi,
I had tried to run Xen on one system using the packages from a Xen
PPA, that seemed to have anything I wanted.
It came with Xen 4.1.2, so I added it, but I need something more
"finished" and "working"
When testing I found so many issues that I'm now uninstalling all of this again:
ii libxen-dev 4.1.2~final-2ubuntu7
Public headers and libs for Xen
ii libxenstore3.0 4.1.2~final-2ubuntu7
Xenstore communications library for Xen
ii xen-docs-4.1 4.1.2~final-2ubuntu7
Documentation for Xen
ii xen-hypervisor-4.1-amd64 4.1.2~final-2ubuntu7
Xen Hypervisor on AMD64
ii xen-utils-4.1 4.1.2~final-2ubuntu7
XEN administrative tools
ii xen-utils-common 4.1.0~rc6-1ubuntu1
XEN administrative tools - common files
ii xenstore-utils 4.1.2~final-2ubuntu7
Xenstore utilities for Xen
It didn't even manage to make Xen the default boot option in the grub2 config :)
Bringing up VMs was also more of a luck thing.
What is the best choice if I want to be actually able to use the
following things:
- dom0_mem *must* work. It's totally idiotic if it doesnt work and i
sit there watching dom0 balloon on each new VM boot, plus the OOM
killer hit a few times during that. How a less than 1.4GB OS install
can run out of Ram whilst ballooning from 96GB to 16GB, I do not know.
>From what I understand this makes all early 3.0 kernels a bad choice
and definitely matches what I was seeing when I tried to set dom0
mem....
- Xen NUMA needs to work since it is a 2socket Opteron
- blktap2
- blkback
- tmem
- Ceph (this means a kernel where I can have very current btrfs and
ceph, most probably not the stock kernel anyway), but this can also
run inside a domU so this is not that important
I guess I'll be going with xen-testing right away and I can also
switch distros if anyone has a recommendation.
(Oracle VM 2.2, 3.0.1 and 3.0.2 unfortunately didn't work on the
system, otherwise I'd be running that instead of trying to run
something.
What are you using for Xen installs that are supposed to *work* on a
larger scale box?
Debian and a selfmade kernel?
RHEL + GitCo?
Alpine 2.2testing was the least of mess of all I tried but
- they're just adding Xen support, so it's not done yet
- only recognized 8 of 24 cpus.

the purpose of libvirt is to provide an abstraction layer hiding all
xen features added since 2006 until they were finally understood and
copied by the kvm devs.
