kernel naming
by Justin Conover
Apparently I missed this tidbit about kernel/name changes, back to the old
style, any reason why yum didn't update them? Guess it doesn't really
matter for final since the installs will use the "new/old-style" name
changes.

PCI problems with Xen kernel on SiS motherboard
by Winston Chang
I just installed FC5-T3 on my computer. With the normal kernel,
everthing works fine, but when I boot into the xen-hypervisor kernel,
kudzu crashes and eth0 won't come up -- it says no such device. USB
ports don't work either, under the xen kernel.
I think the problem has something to do with PCI under the xen
kernel. Running lspci under the xen kernel returns absolutely
nothing, and there is nothing in /proc/pci either. This happens with
both the stock 1955 kernel and the updated 2009 kernel. It also
happened with the FC4 xen kernel, which I why I went to a FC5 test
distribution in the first place...
It's a desktop system, but it has a mobile Athlon XP 2800+ on a cheap
PC Chips motherboard, with a SiS 760 GX northbridge and a SiS 964
southbridge.
Has anyone else seen this or know of a possible fix?
--Winston
===============================================
This is the output when I run on the non-xen kernel (the xen kernel
simply returns nothing for lspci):

Great to hear that! It works! And VMX is created with above steps. Thanks a lot!
Well, it is still a bug. :)
I will do more testing on this version about VMX and XenU.

Latest FC5 Xen (2009) issue
by You, Yongkang
Hi all,
I have downloaded and installed latest Xen, Xen0(hypervisor), Guest (2.6.15-1.2009.4.2_FC5). None Xen packages are still FC5-test3 packages.
When I try to create VMX domain, it reports "Error:.. Connection refused. Is xend running?" But I have start xend.
I use ps -A to check process. I found xenstored and xenconsoled were not running.
Attachment is the xen log.
Would you please share some successful experience, if you have?
Best Regards,
Yongkang (Kangkang) 永康

xenguest-install.py + ks.cfg
by Danny_Trinh＠Dell.com
Hi group,
First, I say thank to Jeremy for "Xen and VNCviewer" problem. Yes, it's
firewall problem.
Second, does anyone try using xenguest-install.py + ks.cfg? Please give
me some hint/instruction/url.
I got tired of sitting to finish guest OS installation(s).
Thanks,

Xen and VNCviewer
by Danny_Trinh＠Dell.com
Hello group,
I try to login to guest OS through vncviewer by doing the following
steps:
- install guest OS
- do "xm create -c /etc/xen/fc5t3-i386-guest1"
- login to guest OS through console; setup vncpasswd, vncserver; edit
/etc/sysconfig/vncserver; make sure tcp 5901, 5801 ports are open; and
"chkconfig vncserver on".
- shutdown guest OS, and restart guest OS back by "xm create
/etc/xen/fc5t3-i386-guest1"
- I go to another machine and use vncviewer to connect to the guest OS,
but I can't.
- However, I can use ssh to connect to the guest OS.
Am I missing some thing? Why didn't guest OS let me connect by using
vncviewer? Is that the limitation?
Thanks,
Danny Trinh
