Scheduled maintenance?
I''m running xen on SLES10SP2. It''s been much more stable than SP1, but I
still occasionally have issues.
For example, one of my servers (8 CPU/32GB RAM) has five sles pv domUs
and five fully virtualized windows 2k3 domUs. It had been up for almost
60 days. Yesterday afternoon one of the sles domU''s stopped responding.
I went to check on it and I couldn''t using

Non-XCP/XenServer frontend or management console
Hi all. Obviously there''s been a lot of talk lately about frontends or
management consoles for xen. All, or most, seem to be for XCP or
XenServer. Is there anything for a group of standalone servers sharing
storage? In my case it''s SLES11 with xen 3.4.1.
I would love to have a frontend for seeing status, starting, and
stopping domains. Provisioning new domains would be an

snapshots on xen
Hi all. I''m using sles11 for my xen servers. I would really like to be
able to do hot snapshots of disk AND memory, and then have these
snapshots backed up to tape or off site for disaster recovery. I''m
thinking this would be done weekly or monthly, not nightly.
Two questions:
1) Is this even possible?
2) I could probably have the systems shutdown to make a clean backups,

GPLPV or other drivers for win2k8r2?
Hi. I have some new 64bit Windows 2008 R2 domU''s running on
SLES11/xen_3.4.2. What is everyone using to get 1gb network performance
on win2k8? I''ve used GPLPV on win2k3, but I see you have to sign the
drivers yourself for 64bit. Maybe that process isn''t difficult, I only
glance at the link from gplpv''s page.
What is everyone using? GPLPV is about the only

SLES10SP2 (xen 3.2.x) vs SLES11 (xen 3.4.x)
I built a couple new servers on SLES11 because I needed to use USB.
Since SLES11 has xen 3.4 packages that seemed like the way to go. I''m
questioning the stability of the two new servers compared to my
SLES10SP2 servers. I''m also questioning the performance of Windows
domUs.
On Thanksgiving day one of my SLES11 servers running 7-8 domUs crashed
and restarted three times. Being

RHEL6 beta vs. Xen
Has anyone yet figured out what it would take to make Xen
run on top of the Red Hat Enterprise Linux 6 beta?
We are heavily invested in Xen under RHEL5 (actually
a redhat clone) distribution, but already the xen kernel
they are shipping with update 4 and 5 is shaky and has bugs
which they don''t seem to be in a hurry to fix.
Basically I am wondering if Redhat 6 is just going to

pci device not owned by pciback.
So yesterday I got was able to get a domU successfully using a PCI SCSI
card. This morning I restarted the host server. When I try to start up
the same domU I get this error:
Error: pci: improper device assignment specified: pci: 0000:0e:04.0 must
be co-assigned to the same guest with 0000:0e:04.0, but it is not owned

How do I make this card owned by pciback on reboot. Do I need to

Can''t install Windows 2003 on SLES10SP1
I finally have a xen server to play with stuff that''s causing me
problems on my production servers. One of those problems is simply
installing Windows 2003. Here''s what I do:
Open virt-manager
set up a new install:
full virt
512 ram
20 gig sparse file
boot off /dev/cdrom
The install starts as you''d expect. When it gets to the formatting I
tell it to format in NTFS.

should restarting xend restart all the domU''s?
I had an issue late yesterday where some windows domU''s were down. The
person who "owns" those domUs let windows updates install and then
restart, which they failed to restart. When I tried to manually restart
them I was getting can''t allocate memory errors.
In the past I''ve had can''t allocate memory errors when trying to bring
up a new domU.

Linux distributions supported by Xen as PVM domUs
Hi:
Reading Red Hat''s Website and a printed manual of RH184 (Red Hat
Virtualization course) I see that RHEL 5 only supports RHEL 4.5 and
RHEL 5 as paravirtualized guests. So I asume this is the same
situation for CentOS 5, right?
What''s the dependency between Xen versions for paravirtualized guests?
I ask this questions because I got this experiences:

Ballooning on SLES11SP1
We have some test servers running SLES11SP1 and we''ve updated to the
latest kernel from Novell: 2.6.32.13-0.5-xen
Since running the updates on these servers our xen ballooning parameters
are not working. Because of memory problems in the past we set dom0 to
2048 meg of ram in grub and set the following parameters
in /etc/xen/xend-config.sxp:

Xen and I/O Intensive Loads
Hi, folks,
I''m attempting to run an e-mail server on Xen. The e-mail system is Novell GroupWise, and it serves about 250 users. The disk volume for the e-mail is on my SAN, and I''ve attached the FC LUN to my Xen host, then used the "phy:/dev..." method to forward the disk through to the domU. I''m running into an issue with high I/O wait on the box (~250%)

GPL PV Intermitent Network Problems
Well, I seem to have developed a strange issue with the GPL PV drivers
in Windows. I''m running Xen 3.2 on SLES 10 SP2 and running some Windows
XP HVM domUs. Most (12-15) of my Windows machines work just fine. Two
of them, though, have started exhibiting a strange behavior with
intermittent network connectivity. Basically, the network starts up and
connects initially. After some

preferred XEN dom0 OS
Hi,
What is the preferred OS to use with XEN, as the dom0 host?
We primarely us CentOS (currently 5.6) but it seems that the native
XEN that comes with CentOS is a bit behind.
What is the preferred OS to run on the dom0''s?

tap:aio not working...
I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

Problem with some win3k3 domUs since crash
Yesterday all of my xen servers went down hard and also lost connection
to ocfs2. 95% of the domU''s came back up ok, but I do have problems with
a few windows domUs. They seem to start ok, but them immediately lose
connection to the network. If I have them on DHCP they are on long
enough to get an address, then they lose connection. If I look at the
properties of the NIC it says 1GB

Re: unable to access Linux HVM via xm console - Couldnot read tty from store: No such file or directory
HVM = fully virtualized. The question is, why are you using fully virtualized domUs? Why not paravirtualized (PV)?
