FC5 domU network connectivity
by dgreen＠CLEMSON.EDU
Trying to set up my domUs with network connectivity. I am running FC5 on
dom0 and FC5 on my two domUs.
My dom0 has a static eth0 and I run the 'network bridge' and 'vif bridge'
in the script at startup. My ifconfig shows (edited for length...):
eth0 Link encap:Ethernet HWaddr 00:E0:81:5D:B1:70
inet addr:130.127.XX.XXX Bcast:130.127.XX.XXX Mask:255.255.254.0
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
peth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
vif1.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
vif2.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link
Questions/Comments:
1) How would I set up my bridge to give out automatic DHCP info to the
domUs? Do I have to run DHCP services on dom0?
2) I would like to keep my 130.127 address on eth0 so I can still connect
to the network, can this still be done and give private 192.168.12.X
addresses to my domUs?
Thanks for any help you can give.

Updated snapshot of virt-manager GUI application
by Daniel P. Berrange
I have just pushed out RPM / tar.gz of a new development (alpha) snapshot
of the virt-manager GUI application. The changes in this snapshot are:
* Fixed DBus service activation & general brokeness
* Added a display of virtual CPU count in summary view
* Fixed alignment of status label in details page
* Make hardware config panel resizeable
* Switch detailed graph rendering to use sparkline code instead of
matplotlib, removing a huge RPM dependancy chain
* Switch to use filled sparkline graphs instead of outline
Although I didn't increment the RPM dependancy, I strongly recommend using
libvirt 0.1.3 if your host is running > 5 guest domains. This reduces the
number of HTTP GETs made by an order of magnitude, improving the response
time / scalability of the virt-manager refresh.
Regards,
Dan.

Xen migration problems
by Cameron Pitt-Downton
Hi,
I've been trying to test out Xen migration, but keep running into a
kernel Oops/crash. It might be my setup or I might be running into some
other problem, but I've searched mailing lists/google and haven't found
anything that has helped.
I'm using 3 FC5 boxes all running the latest kernels, updates, etc:
One box to export a mounted image file generated with
xenguest-install.py via AoE using vblade (have also tried using NFS to
export a directory containing the image file).
The other 2 boxes are running Xen. The guest starts and runs on either
Xen box without a problem, but when trying to do a migration or a live
migration between the 2 Xen boxes, in either direction, I run into the
kernel crash.
The migration actually moves the guest from one box to the other, but it
stops responding via the network, and when logging in using 'xm console'
I see a kernel call trace. The guest kinda still works other than
networking not working at all, so I tried doing a service network
restart, but this causes the guest to totally lock up. If the guest is
rebooted it works fine.
Bellow is the kernel call trace and what is in the destination Xen
server's xend.log.
Thanks
Cameron

Xen - FC6 VT install of Windows XP hangsl
by Algie Seat
I have a Dell 380 which is VT capable. I have installed FC6 as a VT
(unmodified)
Guest under FC6. I'm now trying to install Windows XP PRO as a VT guest.
I'm doing the install from CD. It initially looks like it is going to work,
but after
The drivers are loaded, I get the standard "Setup is starting Windows"
message, but
nothing else after that. A "xm list" command shows the guest is gaining
time rapidly
so it must be in a loop. I saw some info about hitting F5 and choosing
"standard PC"
as the machine type. I did that but still have the same symptoms. I am
completely up
to date with all my packages on FC6. As I also mentioned above, a FC6 VT
guest has
been installed no problem.

heeeeeeeelp on XEN
by Gary Siao
hi gurus
i'm a newbie to xen and like some guidance...
i have an existing machine that has FC5 and i just installed XEN3.0.2.2..
was able to boot the machine using XEN... i know the next step is to create
a guest domain but my problem is how do i create an image of the existing
FC5 since it has some data already (would be nice if you can give me the
actual command).. also once i created an image of the existing FC5, where do
i dump th image file and have xen boot from it...
thanks

Xen changeset is not available on FC6 Test1.
And this info is very useful for fedora-xen user.
Is it possible to build changeset number in xen binary of FC6?
