Hi,
I''m doing some tests of Xen with the latest Intel processors and
I''d
like to run an unmodified linux inside a virtual machine. If possible,
I''d like to be able to install this OS (a version of Scientific Linux,
in case you''re interested) from our PXE servers, but I can also install
it from a DVD image.
I''ve seen several HOWTOs on running Windows like this, so I thought it
would be pretty similar. I basically replaced the Windows CD image for
an SL image, but I haven''t been able to get it to work. I get this:
xenmaster ~ # xm create -c /etc/xen/slc43.hvm
Using config file "/etc/xen/slc43.hvm".
Started domain SLC43
xenconsole: Could not read tty from store: No such file or directory
xenmaster ~ # xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 343 4 r----- 11909.8
SLC43 36 2048 1 -b---- 0.0
The virtual machine is apparently up, but I can''t (or don''t
know how to)
connect to it, it just sits there blocked. The same thing happens if I
use SDL and VNC. I''ve googled to see if I could fix that problem with
xencosole, but with no results. I''ve downloaded a Debian image from
jailtime.org and that works fine (although I don''t see the kernel boot
messages, which is kind of odd).
Can anyone offer some tips?
Thanks,
Alex

http://lists.xensource.com/xen-usersI am also having problems getting the console to connect in a linux on linux HVM. Although I did not find a fix for this I did find a work around. I simply enabled VNC and used that to connect to my Linux DomU to complete the install. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

OK, xm shows a process but I bet it is just an "empty shell" as there is this error message in your debug output: No such file or directory: ''/dev/hda'' I''d go for this and try to find out the reason. If you want you can post your config file here.

It might work better with xen stable or unstable. Alexe: Ben Thomas sent me some more info how he did id, but I didn''t try yet, it involves using unstable, which I am a bit hestitating to do. I can forward the info to you if you are interested. Henning _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I''ve commented it out.> disk = [ ''phy:/dev/xenfs/slc4root,hda,w'', > ''file:/root/SLC43_i386_dvd.iso,hdc:cdrom,r'' ]That didn''t work, I got this: Error: invalid literal for int(): :cdrom Taking off the cdrom line leaves me in the same situation as before. xm list says the VM is running, although it is blocked. xm console doesn''t work with HVMs (right?), and I don''t know how else to connect to the VM, since SDL and VNC don''t seem to work either.
