IIRC I once managed to also have two DomU's and having the third crash my system, but can't remember how I managed that.
This is my CPU, AFAICS it has HT support, but either I deactivated it in the BIOS or it's not active for other reasons - but haven't changed that ages ago, so IMHO my issue is not HT relatead. AFAICS the DomU Kernels do not cause the crash - IMHO it does not matter what kind of DomU Linux you start, only the Dom0 Kernel matters. It might even not matter if the DomU is Linux - anybody tested with BSD? (I don't have a current CPU :(, thus no VX support) FYI: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.40GHz stepping : 7 cpu MHz : 2880.882 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe bogomips : 5764.73 -- Dom0 crashes upon start of second DomU https://launchpad.net/bugs/71348 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
