Ubuntu 10.04 DomU Xen 4.0
Hi Everyone,
How does one install Ubuntu 10.04 DomU in PV mode when running Xen 4.0? My Dom0 is also running 10.04.
Can I still use the CD?
Thanks

HVM Network Interfaces
Hi Everyone,
In my HVM guest''s config file, I have given my guest 3 interface. I have
called them fw1, fw2 and fw3. I have joined each interface to a bridge
on the Dom0. This does appear when I do a "brctl show". However, there
are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where
x is the domain ID for the guest). Furthermore, I am only able to run

VT-x not found..
Hi Everyone,
I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide:
http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/
Now, using the new kernel that it gave me, the system doesn''t seem to be
able to detect vt-x..
In virt-manager, Local Install Media and Network Boot are greyed out..
Any ideas?
Thanks

Dom0 cannot see network when bridge is enabled
I''ve seen a lot of threads w/ similar problems, but none have posted a
resolution.
I am using Debian 4.0r1 (Etch). I was using the xen packages from
stable, but have tried w/ testing as well and the problem persists.
http://pastie.caboo.se/95144
Host is 10.0.0.20 on network 10.0.0.0/24.
Dom0 is thus 10.0.0.20
DomU is 10.0.0.30
When the bridge is enabled, DomU can ping everything.

SSH Console issues with Ubuntu
Hi,
When I login to a Ubuntu 10.04 virtual machine instance running in
Xen through SSH, the console''s lines are clipped at the middle section of
my 15.6" screen. I''ll be glad if somebody can suggest a fix. This is turning
out to be very annoying.
Thanks,

terrible time implementing it.
My setup:

RAM security
Hi Everyone,
In Xen, is a DomU able to access data in RAM which a previous DomU has stored in the past, but didn''t "zero" it?
I understand that this is a problem with physical disks (using phy:/), just wondering if the same stands with RAM
Thanks

Xen Networking problem!
Hi,
I ''ve got a CentOS 5.2 server running xen 3.0 with 2 DomUs also running
CentOS 5.2.
All my boxes are up-to date.
I''m experiencing trouble with networking.
Dom0 can reach the outside world when no DomU are started. It can also
reach the outside world when only one DomU is running.
The troubles begin when I start the second DomU. At first, this new
DomU, called DomU2,

Re: [Xen-devel] xen 4.1.2* dhcp issue/bug when installing/booting HVM domU domains (CentOS 6, unbuntu 11.04 server). Debian/OpenSolaris work fine.
Thanks a lot for your hints Pasi.
Due to your suggestion I open a new thread here.
I have tested with model=e1000 (HVMs). As HVM configs are identical (not
iso images and LVM volumes) I guess it is a xen 4.1.2* issue .. or just
involved domU OS-kernels (however as it is HVM it should not play any role)

DomU networking problem in opensuse 11
Hi,
Creating a new domain is a lot easier in opensuse 11. I follow the instruction on the website and build a virtual machine which uses opensuse 11 as well (I installed it from iso image). Everything works fine except the network. I cannot access the Internet from DomU. Here is some information.
P.S. the DomU id is 1.

Debian Squeeze hangs with kernel 2.6.32-5-xen-686
Hi all!
After upgrading to Squeeze, I am watching a Xen VMHost that after a
while it hangs. This did not happen when I was using Xen with Debian
Lenny (in this case as with Squeeze, the Xen components are from Debian
repositories).
In each case I connected a keyboard and monitor to the computer and the
screen remained black without answering any key.
This problem seems to also affect domUs,

netback/loopback.c creates them.
It''s effectively a point to point link, allowing domain 0 to connect on
to the bridge in the same manner that other domains do. (before, packets

[SPAM] Xen bridge network issue
Hi,
I have taken the long and winding road and indeed it lead me to your door. I
need your help, please.
My Xen includes 2 guests. Xen itself (10.2.0.52) gets free access to the
outside world and to its guests.
Both guests however (10.2.0.54/10.2.0.55) see each other but stay under
house arrest!
Not a single ping manages to go past the bridge (xenbr0) and get an answer
from the default gateway

Convert HVM to PV
Hi Everyone,
To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter?
Or is there something else I am missing?
Thanks

Install ubunto domU
Dear *,
I''m more used to work with RedHat like OSes. Still, I did not denied the
request from a user who wants a domU based on ubunto. I usually use
virt-install to do the job, with a script similar to this one:

outgoing domu network dies after a while
I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine
for a few months.
This past weekend it suddenly started to act up and after some
troubleshooting I can now say that it seems like the guests(domU) loose
the outgoing network pipe, from the console I can see that the TX
counter is stuck at the same value but it''s no errors. It behaves as if
