[Xen-devel] dom0 reboots (reproducably) when installing rpms in domU
Hi There! I''m using 2.6.10-xen0 on debian with 2.4.29-xenU and scientific linux. When installing a large RPM on the sci-linux, the dom0 reboots reproducably. No log info found in /var/log/[syslog|dmesg|messages]. My guest filesystem in inside a file which is nfsmounted. Is it stupid to use 2.4 on 2.6? -- Marcus _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

No > log info found in /var/log/[syslog|dmesg|messages].Can you get a serial line attached to this machine? Failing that, can you try doing all this whilst logged into dom0''s text console - we might see some sort of panic message come out there (if X is running in dom0, it''ll hide the panic message). Also, what release of Xen is this? 2.0.5? 2.0-testing? How did you install it (self build, vs RPMs).> My guest filesystem in inside a file which is nfsmounted. > > Is it stupid to use 2.4 on 2.6?Not at all. It should work just fine.

The dom0 had 64MB only.
