Dear List,
Does anybody successfully start an UML on a Dell PowerEdge 2850? The
maschine has an Intel Xeon CPU 3.0 GHz (this meas x86_64 architecture) with
hyperthreading, therefore prozessor shows twice.
I tried different setups and patches, but wasn't successful. If I succeed to
compile, the UML always crashes after mouting the rootfs with a Kernel panic
(dump at the end of the mail)
As host I used a stock 2.6.12.5 kernel from Kernel.org and in another try
the same kernel patched with skas-2.6.12-v9-pre7.patch
As guest I used the stock kernel patched with either uml-2.6.12-bs11.patch
and uml-2.6.12-bs9.patch with mostly default config file. I had to disable
"Symmetric multi-processing support" because the guest kernel (make linux
ARCH=um) does not compile with this setting enabled:
