Hello, I try to get a Nvidia Quadro PCI-E graphics card to work with xen in Dom0 with the binary nivida-drivers. I use the xen-2.0-testing tarball with kernel 2.6.12 and the nvidia driver package NVIDIA-Linux-x86-1.0-7676-pkg1. The nvidia kernel module compiles without errors but when I try to load it segfaults. Is it possibly because the tls-libs are disabled? Has anyone managed to get the nvidia drivers to work with xen? Or is there a general problem with xen + nvidia? Thanks, Frank _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Anthony, that''s weird, i did compile my own (xen 2 based) dom0 kernel from source, then proceeded in installing the nvidia drivers (using the .sh script they provide) Obviously, no pre-made kernel modules were available, but the script was able to compile its own module (with the correct links in /usr/src). I can''t say i''ve used the graphic features of this system much (it''s my server), but i did not hit any issues with this, works like a breeze.

On nvnews.net, I wrote a polite request for Xen support. Please see the thread at: http://www.nvnews.net/vbulletin/showthread.php?t=60125 Unfortunately, due to major HW/SW upgrades, it''ll be a short while before I can participate on the forum myself. Often, vendors are accused of not showing interest in Linux, so since Nvidia has now shown Xen interest, I believe it''ll be A Good Thing if some from this list would signup on nvnews and participate. -- Kind regards, Mogens Valentin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

If Nvidia developers are interested in supporting Xen, you should direct them to xen-devel and they are certain to get the help they need.

Why I didn''t think of it is beyond my capacity ;) Anyways, I''ll do just that. To be fair, I merely asked Nvidia to think (alot) about Xen support; the thread on nvnews is still in it''s infantry. -- Kind regards, Mogens Valentin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hello list,
I am just at the beginning of installing Xen. After two days of trying I
finally managed to boot the xen0 kernel. Now I am trying to create my first
domain. Since the system is a Raid system, I know there is a problem with my
root entry (I had these problems with the xen0 kernel as well in the
beginning) I receive this error message when trying to create the domain
with "xm create -c xmjan1 vmid=1" (system is FC4 on Dell 450 WS, 2
CPUs,
SATA Raid, 2GB RAM):

# Optional ramdisk.
ramdisk = "/boot/xen-3.0.jan.img"
# The domain build function. Default is ''linux''.
#builder=''linux''
# Initial memory allocation (in megabytes) for the new domain.

# Optionally define mac and/or bridge for the network interfaces.
# Random MACs are assigned if not given.
#vif = [ ''mac=aa:00:00:00:00:11, bridge=xenbr0''
]
#----------------------------------------------------------------------------
# Define the disk devices you want the domain to have access to, and
# what you want them accessible as.
# Each disk entry is of the form phy:UNAME,DEV,MODE
# where UNAME is the device, DEV is the device name the domain will see,
# and MODE is r for read-only, w for read-write.

]
#----------------------------------------------------------------------------
# Define to which TPM instance the user domain should communicate.
# The vtpm entry is of the form

#hostname= "vm%d" % vmid
# Set root device.
root = "/dev/mapper/VolGroup00-LogVol00 ro"
# Root device for nfs.
#root = "/dev/nfs"
# The nfs server.
#nfs_server = ''169.254.1.0''
# Root directory on the nfs server.
#nfs_root = ''/full/path/to/root/directory''
# Sets runlevel 4.
extra = "4"
-----------------------------------8<-----------------------
Can anyone point me to a solution, e.g. where to look to determine the
correct root drive/dev in a Raid system? Since this is my first machine with
a Raid system installed, I am a bit stuck here...
Thanks in advance

my understanding is that you want to hide the complexities from domU systems... so if you want the domU to have a raid1 filesystem, you export the raid1 device to the domU but call it /dev/sda1 or something like that... so the domU just sees a block device, it doesn''t need to know that it is actually a raid1 mirror. Obviously, you can go the other way, and let it see both partitions and do the mirroring itself, but it is _much_ simpler to just show the domU a simple block device. -Tom On Mon, 21 Nov 2005, Jan Peters-Anders wrote:> Hello list, > > I am just at the beginning of installing Xen.

Tom, thanks for the reply. My problem is not quite what you expected, though. I just do not know, what my root entry in the conifg file should look like, so that the domain is able to boot. I am at a somewhat lower level than you expected me to be ;-). BTW: This is a raid5 filesystem and I just do not know what the correct entry is so that the xen domain is actually _able_ to _find_ the device in the first place. Or do I misunderstand something very fundamental here?
