Simple testing results for Xen and VMX on FC5-test2.
by You, Yongkang
Hi all,
I have done a simple checking for Xen and VMX on FC5-test2. Basically, I can create VMX on FC5-test2 IA32. But FC5-test2 IA32e (x86-64) doesn't provide Xen and Xen0 kernel, so didn't do Xen and VMX testing for it.
Beside of testing Xen and VMX, I also found some issues about installation, which I have updated the bug #179078 as a NB. The following is the testing results only for Xen and VMX.
=========================
1. *** IA32E hasn't RPMS about Xen hypervisor and Xen0/XenU kernels. __FAIL__
2. *** In order to boot up IA32 Xen0, I have to add pci=noacpi as the boot
parameters of Xen0 kernel, or system will hang when initial PCI. I don't know if it is only related to my Machine. __FAIL__
3. After install IA32 Xen RPMs, I can see /boot/grub/grub.conf has been changed
with Xen kernels. __PASS__
4. *** /usr/lib/xen/boot/vmxloader isn't in the RPM package, so VMX Guest
couldn't be created. I suspected build system hasn't bcc, it is from DEV86
package. __FAIL__
5. After copy a useable vmxloader to the destination, IA32 VMX Guest can be
created successfully! __PASS__
6. VMX has good network connection and Xwindows started. __PASS__
7. XenU can be created and works well. __PASS__
8. Couldn't get Xen Changeset by "xm info" or "xm dmesg".
9. The new kernel names of Xen/Xen0/XenU seemed a little confused. E.g. the Xen0 name is like vmlinuz-2.6.15-1.29_FC5hypervisor. I thought hypervisor is for Xen.gz. Xen0 is the Service OS.
==========================
Any comments please let me know. But I will have 8 days holiday from tomorrow, so emails reply might be slow and occasional.
[FYI] We are planning to do more testing for FC5-test3.

Hang when starting xenU using riel's packages
by Yip Wai Peng
Hi all,
I am using kernel-xenU, kernel-xen0, and xen-3 from
http://people.redhat.com/~riel/xen_for_fc4/. xen0 boots up fine, but when I
start xenU, it hangs at the below screen. I have already moved /lib/tls out
of the way.

I would appreciate any help given. Thanks!

I am very glad to hear it is coming. :) Hope we can see it in the FC5-test3 x86_64 packages.

I am not sure how common used my machine is. :( But it can work with latest Xen + 2.6.12 kernel in the RHEL4u2 or FC4. So the new problem may be related with new kernel 2.6.15? I can fire a new bug about it. My testing machine is SMP enabled.

Em. If we can found some changeset info in changelog or other way, it may bring some help to customers and developers. :-)

Yes, I recognized the Xen hypervisor and dom0 kernel are coming from 1 package. But you see, the dom0 kernel is named vmlinuz-2.6.15-1.29_FC5hypervisor. I mixed it with Xen.gz at the beginning. Why not named it like vmlinuz-2.6.15-1.29_FC5Xen0 for easily distinguishing. :)

Simple Instructions on networking
by Randolph Hill
I am new to Fedora and Xen. I have everything up and running with the exception of being able
to access the network from my guest domain. I am looking for some simple instructions to get me going.
My system is connected to a Linksys Wireless router. I would like to have internet access from the guest domain.
Pointers are appreciated.
Thanks

Enabling NFS root for Xen guests in FC5
by Fraser Campbell
Hi,
CONFIG_IP_PNP and suboptions as well as CONFIG_ROOT_NFS should be
enabled in Xen guest kernels in order for NFS root to be used in Xen guests.
At least kernel-xen-guest-2.6.15-1.29_FC5 and
kernel-xen-guest-2.6.14-1.21_FC5 do not have these options enabled. I'm
hoping these options can be enabled in future builds or were they
intentionally turned off for a reason?
Thanks,
Fraser

Ack, apparently, we were both working on similar things. I've actually
updated the FC4 one to include a much better description of how to do
things in FC5 taking advantage of the installer functionality rather
than using yum and chroots. This is far better as it allows things like
SELinux to work and gives you a much more manageable system. See
http://fedoraproject.org/wiki/FedoraXenQuickstartFC5 for the write-up
including this information.
It probably makes sense to canonicalize on this as it is going to be the
more supported method of installing guests with FC5 and later.

Draft Xen Quick Start for FC5
by Gawain Lynch
Hi All,
I have put up a Quick Start page on the wiki [1] for FC5. This document
is based on the original one for FC4 but is updated to take into account
changes in FC5/Xen 3.
I currently consider it draft but it Works For Me (tm). I would be very
grateful if some of you could take it for a spin and let me know any
issues/errors/omissions you find.
It is not currently linked to the main Xen Wiki page, I'll do that once
I am happy that I have it right.
Take care,
Gawain

documentation/packages for xen on FC 5?
by Sam Folk-Williams
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
I'm trying to get up to speed on xen from a user/support perspective.
I've found the howto for FC 4 (and the link to the packages on Riel's
people page) very helpful. Is there something similar for FC 5?
Generally I'm wondering if the packages installed via yum from the main
devel repos will work, or if someone has a link to packages for FC5.
Also, would be more than happy to help contribute to documentation for
the project.
Thanks,
Sam

PAE enabled Xen?
by Fraser Campbell
Hi,
I'm wondering if there are any plans to provide a PAE enabled version of
xen, kernel-xen-hypervisor and kernel-xen-guest?
We are doing extensive testing with FC5 and large memory machines (8GB
so far).
For now I will track down the source RPMs and look at rebuilding them.
Thanks!
