Domain-U failed to start when Domain-0 reboot
by Muzammel Asghar
Hi guys i am facing some strange problem in xen. I used xen version 3
in fedora core 8 in routed mode. I create 5 vm's, the problem is when i
reboot mother
domain-0 first two vms boot and shutdown and rest other 3 vm's
are boot properly. But after that i manually start 1st and 2nd vm they
start fine, i don't understand why they not start automatically when
domain-0 boot but manuall start of these vm's are fine
here below the logs of /var/log/messages

Using Wireless Connection In KVM
by Robert L Cochran
How can I get my Fedora 10 guest to use a wireless connection? Do I need
to configure a wireless "bridge" adapter? That is, if the wired adapter
bridge is ifcfg-eth0 referencing "br0" perhaps I need a second named
ifcfg-wlan0 referencing "br1"?
In short: does anyone have wireless working for Fedora 10, KVM guests?
If yes, can the configuration details be shared with me? I'm dying to
use wireless in my guest. Laptops were never meant for long trailing
wires if you ask me...
Thanks

Fedora 8: Empty shared physical device?
by Siddharth Wagh
Hello all,
I am in the process of creating a VM and am on the "Connect to host network
step". Since my machine is connected via wired ethernet, I wish to choose a
physical device to connect to, but am getting an empty shared physical
device list. Any hints on how to populate it?
Thanks & Regards,
Siddharth Wagh

rawhide domU on RHEL5.2 dom0?
by Jon Stanley
I can't seem to make a rawhide domU work on a RHEL5.2 dom0, because
virt-install doesn't think that there's a valid tree. Looking at it,
there is indeed no images/xen in the tree, are we using the standard
kernel for DomU's now, or is F10 not going to be supported as a domU?
This is on x86_64.

KVM Networking Question
by Robert L Cochran
To my pleasure, I was able to get two different virtual machines running
pretty quickly. I installed Fedora 10 x86_64 on my new laptop with the
Virtualization package group and as little else as possible. Then I
updated the system (so now I'm using kvm-74-6-fc10.x86_64), started the
graphical Virtual Machine Manager, and built a guest for Windows XP
Professional and a second guest for Fedora 10 x86_64.
I want the Fedora 10 guest to fetch an IP address of 192.168.1.115 from
the dhcp server running on my network. Virtual Machine Manager seems to
be creating it's very own dhcp server and assigning network addresses of
192.168.122.2 and higher. So I can't ping the guest I just created from
a host on the 192.168.1.0 network.
The networking behavior VMWare gives me results in my virtual machines
getting their addresses from the dhcp server on the 192.168.1.0 network,
so the host IP I'm expecting for a machine is the one that is assigned
and used.
How do I change the networking in Virtual Machine Manager to simply pass
all the dhcp calls to my network? Or is there a good reason to let the
Manager do its own 192.168.122.x network?
Thanks

How To Test Dom0 Xen Support In Fedora 10
by Robert L Cochran
Hello,
I'm an experienced IBM mainframe programmer with just a little C and
Java coding experience. I have no experience in the programming part of
virtualization. I currently do have CentOS 5.2 running as a guest under
VMWare workstation (an older version which is about a year old, running
on a Fedora 7 host. And yes, I know Fedora 7 is long out of date.)
I would like to jump in the water and get my feet wet, though. Can
someone like me test Dom0 Xen support in Fedora 10? If so, is there a
web resource somewhere spelling out how to get started with testing? I
will need the steps involved in patching and building a test kernel
pointed out to me.
I just bought a new laptop, the Dell Latitude E6400 with the Intel P9500
processor. I think this processor has virtualization technology (vmx
extensions?) so the hardware for testing is there.
Thanks
