We have tested the latest xen on VT platform with Intel 915/E8500 chipset. Three platforms(32/pae/32e) test all are based on SMP, It means that we boot up SMP guest OS in VMX. Here is the test summary: Issues: + This bug fixed: Creating 32PAE SMP guest on 32pae/64bit platform crashes xen0 - Creating 4 VMX simutaneously on 32 platform will hang xen0 - Sometimes build base kernel 2.6.16 in IA32SMP guest fails on 32bit platform.

[this is by far the >most tested combination]Hi Ian, This issue happened on both 32bit (none pae) hypervisor and 32bit pae hypervisor. We didn''t catch it in 32e (x86_64) hypervisor. It is to create 4 VMX at the same time. The command is like: "xm create vmx1; xm create vmx2; xm create vmx3; xm create vmx4". Sometimes Xen0 won''t hang. But the 4th VMX can not be created up. Xen0 reported: "Error: Device 768 (vbd) could not be connected. Hotplug"> >> > - Sometimes build base kernel 2.6.16 in IA32SMP guest fails >> on 32bit >> > platform. >Which hypervisor does the error occur on?This issue only happened on IA32 hypervisor (None-PAE).

Xen0 reported: "Error: Device 768 (vbd) could not be connected. Hotplug"I can start four VMX guests like this without any problem (on 32bit non-PAE Xen). Can you give some more details -- what guest OS are you using, how much memory per domain, how many VCPUs per domain?

Xen0 > reported: "Error: Device 768 (vbd) could not be connected. Hotplug"Please can you follow my suggestion of starting the 4th guest from a text mode console. Even in the case where dom0 doesn''t hang but the domain fails to start please can you send the xen logs from /var/log/. Does starting a 5th simultaneous guest make the problem more or less likely?

Tim, We found that in some hardware, 4 VMXs works well too in 32b non-PAE xen. Maybe this is a hardware specific issue.
