-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, when I''m starting a second guest-system Xen is crashing while the guest is reporting kernel panic. The same guest ist booting well, when starting up alone. Environment is a Debian-System with 2.6.17-xen-k7 (also tried 2.6.18-xen-k7) on K7 AMD CPU. The guest have a setup with small memory (64MB). Is there somthing to fix with the xen-configuration? thanx for hints GW -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFR6jcWgcH1Ne3oGIRAkJZAJ46+Ns9a+XsuyD2b4ehsLTXivSh8gCfRdZs b09cY7NJRZD90EtczGh563w=4081 -----END PGP SIGNATURE----- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks for the detailed explanation of your problem. Now: What are you expecting us to say? Defective RAM maybe?

Defective RAM maybe?I tried to find out what the reason maybe and off cause also considered the memory-chips. But exchanging them didn''t help. Also I changed the whole machine, set up a complete new system - and got the same result. Both machines had the same 2.6.17-k7-kernel (while under the 2.6.18 Xen didn''t like to start anyway), and now I''m questioning, if this xen-k7-kernel is having a problem. This kernel comes from the related debian-package. Thus the question: are these kernels running well within other Xen-Systems?> > The same guest ist booting well, when starting up alone. > > Environment is a Debian-System with 2.6.17-xen-k7 (also tried > 2.6.18-xen-k7) on K7 AMD CPU. > > The guest have a setup with small memory (64MB). > > Is there somthing to fix with the xen-configuration?_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

When I start a second VM the host gets a kernel panic and a few seconds later reboots the host.

Now got rid of these problems by upgrading the kernel from 2.6.17 to 2.6.18-k7. With this kernel Xen seems to run the way it should.

Now I started 3 guests without trouble. Before I tried installing the Xen-binaries (after removing the debian-xen-installation), but it refused to boot fully ("..not syncing"). Then installed the new debian-2.6.18, and its running. CPUs we''re trying at our test-machines are Duron and AMD Geode 1750.> Can you send us your logs, please?I''m sorry, but can''t find any related log-entry: xend.log only notes <domU> unpaused just before the crashing. The same with the kernel-log.> > > The same guest ist booting well, when starting up alone. >> >> Environment is a Debian-System with 2.6.17-xen-k7 (also tried >> 2.6.18-xen-k7) on K7 AMD CPU. >> >> The guest have a setup with small memory (64MB). > > > Some systems don''t work well with small memory, but if it runs as a > single > vm, it should be O.K. > > Henning >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

" So you''re not having the same problem. I know, when the host machine crashes and has a kernel panic there aren''t many logs to post here :) Please open a new thread and tell about your environment, maybe someone has an idea...
