Booting Xen of the network
You know you can't just boot Xen of a PXE server, it's not a normal linuxkernel your booting , so you need
a multibootloader, such as the COM32 one that is packed in recent syslinux versions.
While playing with openQRM I ran into an odd problem. I still haven't figured out the actual problem.
I saw COM32 Multibootloader v0.1 taking a Xen from boot/xen.gz
then the module boot/res-1-kernel and later boot/res-1-initrd.img ...
after loading the last one and about 2.5 lines of dots I got
Booting: MBI=0x000100d8, entry=0x00100000
Then nothing and it seemed like my machine locked.
The fix was to upgrade the multibootloader to the one that is in Syslinux 3.11 from there on.. no more problems.
