Xen networking
by Tom Leasure
Hello all -
I have a guest domain running that I want to run a web server on (Both are
FC5). The guest has its own IP and I can ssh into from anywhere. It is able
to download anything from the network/Internet However, I can't get to it
via port 80 from the browser. The network firewall has port 80 open for that
IP. I have apache setup and configured properly.
Do I need to configure something with domain0 in order for web traffic over
to port 80 to reach the guest domain? I suppose port 22 for SSH was
configured by default?
Any help would be appreciated.
Thanks

VNC and FreeNX disrupted is lost under XEN Dom0 kernel (mouse and keyboard are frozen)
by Jan Andrejkovic
Hello,
I thought there is a pobrlem between FreeNX and FC6 XEN Dom0 kerenel but now
I discovered that there is also the same problem between VNC server and XEN
enabled kernel (vnc-server-4.1.2-9.fc6 and 2.6.19-1.2895.fc6xen). Does
anybody have the same problem?
Do you know any workaround?
Thank you,
Jan

Strange video problem with Xen kernel and undocked laptop
by Michael DeHaan
Computer: IBM T43
kernel: 2.6.19-1.2895.fc6xen
When docked, the laptop seems very happy, and I can use X/Gnome/etc fine
... undocked, the entire screen goes black right after logging in via
gdm and I can't even switch to a tty. Booting a non-Xen kernel allows
full use of graphics, and I can find no relevant enteries in
/var/log/xen/* that indicate what might be going on.
Any ideas or has anyone else experienced similar?

If only SLES didn't suck - and Novell actually kept their promises.
But I could be wrong, maybe they'll be better now that they have
reliable partners like Microsoft...

Hi,
i'm using virt-install and it runs successfully with that command:
virt-install -n xengrid2 --vcpus=1 -r 256 -s 4 -f
/media/disk/iso/xengrid/xengrid2 -l
ftp://mirrors.hpcf.upr.edu/pub/Mirrors/redhat/download.fedora.redhat.com/...
-p --nographics
now, i have a question. What's the kernel image and initrd file used for
virt-install in order to carry out the installation process? I need that
information because i want use the cobbler/koan tools in order to
provision virtual machines remotely, but when i submit the command
koan --virt --server=136.145.116.114 --profile="xentemplate-profile"
i got that:

Fwd: FreeNX session - mouse and keyboard frozen under XEN Dom0 kernel
by Jan Andrejkovic
Hello FC XEN list,
I already sent this e-mail to main Fedora mailing list but now I realised it
will be better to send it to XEN dist list:
I have FC6 installed with latests patches (I use GNOME and XEN kernel
2.6.19-1.2895.fc6xen) with all current updates. I installed FreeNX from
fedora extras and I tried to connect to this Dom0 kernel from Win XP client
( 2.1.0-16). The connection was successful but after a few seconds I lost
the control using mouse and keyboard. I saw the screen, Gnome was just not
responding. Even when I tried to resume abandoned session I saw the dektop
again but I was not able to re-gain the control.
Then I removed freenx downloaded from extras and I installed newest rpms
from nomachine web-site:
nxclient-2.1.0-11.i386.rpm
nxnode-2.1.0-15.i386.rpm
nxserver-2.1.0-18.i386.rpm
and for compatibility I had to add:
compat-libstdc++-296-2.96-138.i386.rpm (downloaded from rpmfind)
However the result was the same - sesssion gets frozen after a couple of
seconds.
Then I tried to use older kernel - 2.6.18-1.2798.fc6xen with the same result
- once I just moved the mouse over gnome main menu the session was frozen.
(I did not make so much observations yet but I think it is somehow related
to mouse because when the session is waiting for the text input it will not
get frozen so easily.
In final I tried non-XEN kernel 2.6.19-1.2895.fc6 and it seems to be working
fine.
Does anybody notice the same behaviour? I would like to try GUI manager to
setup some domains but I can't... (Well, VNC is probaby the option...)
Thank you,
Jan

Trouble installing VM under Xen Server
by EyalRi＠clal-ins.co.il
Hi,
I am trying to install Xen VM (redhat) under Xen Redhat 5.0 beta.
Using virt-install I have entered the following:
What is the name of your virtual machine? xen01
How much RAM should be allocated (in megabytes)? 2000
What would you like to use as the disk (path)? /xen_vm/xen01.img
How large would you like the disk to be (in gigabytes)? 10
Would you like to enable graphics support? (yes or no) yes
What is the install location? nfs:abc:/abc/Unix_Install
Starting install...
ERROR: Invalid NFS location given: [Errno 2] No such file or directory: '/var/lib/xen/xennfs.sOAI67/images/xen/vmlinuz'
The "abc:/abc/Unix_Install" is pointing to nfs mount point with Redhat ISO`s (.iso)
Tried using ftp,http,nfs - with no success
Any idea what could be the problem ?
Regards,
Eyal

Re: Having issues with Windows 2003 as a guest

I'll try again. Can anyone tell me why VNC consoles for Win 2003
fully virtualized guests won't accept keystrokes and why SDL-based stuff
never even opens a console window?
I have GOT to get this crap running! I've been doing Linux for as long
as it's been around so I'm not a complete idiot. Can someone offer
some help? Please? I'm getting desperate!
