Xen and para-virtualisation
by LIMOGE
Saclay ce 24 avril 2007
Dear All
I need (halas) to run a Windows on my fedora powered workstation.
Can anybody tell me if the Xen para-virtualisation tool can really host
Windows, and what are the adaptations to be done to get a working one on
a machine which doesn't has the Intel VT technology ?
Many thanks for your kind informations.

Yves,
Paravirtualization means that the guest OS is modified to be virtualized.
To run Windows as a guest OS with Xen, assistance from the processor is
needed. An Intel-VT or AMD-V processor is required.

No.

Request microsoft to opensource windows code so that we can modify it to
work as a paravirtualised guest.

FC7 xen status question.
by Naoki
Howdy,
The xen kernel normally lags behind the mainstream fedora, right now
it's about a month older :
$ rpm -q kernel kernel-xen
kernel-2.6.20-1.3071.fc7
kernel-2.6.20-1.3094.fc7
kernel-xen-2.6.20-2925.5.fc7
So I'm wondering if there is a technical reason for this and if the
versions will sync before FC7 release?
Cheers,

LVM backed storage
by Adrian Revill
Hi,
I have created a DomU using a logical volume created on the Dom0 called
node-image, and i can see it as the device /dev/VolGroup00/node-image
When i installed the OS i created a custom disk layout of a single ext3
/ partition. (an odd layout, but this is for a diskless client image)
I would like to be able to mount the /dev/VolGroup00/node-image on Dom0,
but i cannot work out how to create the device nodes for the partition.
So i thought i could use the xm attach-block command
xm attach-block 0 /dev/VolGroup00/node-image /dev/node-image ro
This said it had created the device but i could not see it in /dev on Dom0
Does any one know how i can mount /dev/VolGroup00/node-image partition 1?
regards
Adrian

where are disk config docs?
by Tom Horsley
There are apparently an awful lot of different ways to define
disks for VMs, but there are apparently no docs describing
them anywhere :-). Where do folks find out how to do all the
things I see references to in the mailing lists (xenblk drivers,
tap:aio, xvda, I can find millions of hits on google, mostly
in patches, but I can't find anything resembling documentation).

USB2 on XEN
by misi e
Hello,
I have 2 questions, which are interrelated:
1. will USB2 will be soon supported by XEN.
2. is there any project to port the PCI "emulation" to windows, so that PCI
cards would be seen in windows domu?

AoE with Xen
by Andy Burns
I'm considering using AoE with Xen, my setup would be vblade on one
FC7 storage server with mdraid over 6x SATA disks, and two xen hosts
with FC7 using aoe+aoetools, using eth1 on all servers to a separate
VLAN for SAN traffic, eth0 used for normal LAN traffic, all gigabit.
I'm wondering does it make more sense to slice up /dev/md1 on the
storage server with LVM and then serve multiple /dev/VGxx/LVxx block
devices with individual vblade processes using their own AoE
shelf/slot ID to individual dom0 (or direct to AoE in domU)?
Or to serve the whole /dev/md1 using a single vblade process on the
storage server and then use CLVM or GFS on each xen dom0 to slice up a
single /dev/etherd/e0.0 in a coordinated way?
My thoughts are that using a cluster filesystem would save the hassle
of starting/stopping vblade processes whenever resizing LVs and any
associated confusion of shelf/slot IDs
But I'm not sure of the overhead of cluster filesystems, does DLM only
get involved for maintenance operations on LVs, or for all I/O
activity?
Thoughts welcome from anyone using (or having attempted) either approach ...

Re: [Fedora-xen] cannot boot into xen kernel
by Yuming Fei
Here are the flags in the cpuinfo file, looks like the CPU has the PAE support:
$ grep pae /proc/cpuinfo
flags : fpu vme de pse tsc msr pae mce cx8 mtrr pge mca cmov pat pse36 mmx fxsr sse up
or, maybe I am missing something here? Any helps will be appreciated.

I seem to recall that FC6 has a PAE kernel, and many/most laptops don't have
PAE support in their CPUs.

rhel 5 hvm install freezes
by Tom Horsley
I am trying (mainly for experimentation purposes) to install rhel5 (x86_64) fully
virtualized as a guest under Fedora core 6 (x86_64) Dom0.
I've got the rhel5 CD images mounted where apache can see them, and I tell
the xenguest-install script to use the images/boot.iso file as the install image.
I get started fine, tell the installer to use HTTP, point it at the apache server
running on Dom0, and it gets a good way through the install, then the virtual
video freezes up, the virtual mouse no longer moves, etc.
This sound familiar to anyone? Any particular rocks I ought to start looking
under for information about what might be going on?
