Hi
I have a kernel panic when loading bhyve hypervisor kernel module.
These are the steps I followed
1. First I installed Freebsd 9 on my machine which has Intel-x86_64 and 8Gb
Ram
2. The following output from dmesg.boot confirm that vmx is enabled in the
machine.
PU: Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz (2394.06-MHz K8-class
CPU)
Origin = "GenuineIntel" Id = 0x20655 Family = 6 Model = 25 Stepping =
5
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
Features2=0x29ae3ff<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,POPCNT,AESNI>
AMD Features=0x28100800<SYSCALL,NX,RDTSCP,LM>
AMD Features2=0x1<LAHF>
TSC: P-state invariant, performance statistics
3. Then I checked out the latest code from svn://
svn.freebsd.org/base/projects/bhyve/
a) I built world and kernel
b) Followed the steps in
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
(25.7.1
The Canonical Way to Update Your System) to install the new kernel and to
install the new world.
c) Rebooted to the newly built kernel.
4. I wanted to give 4gb to the host kernel and the remaining memory for the
guest. So I set hw.physmem to "0x100000000".
5. Rebooted the host so that hw.physmem takes effect (Following
http://people.freebsd.org/~neel/bhyve/bhyve_instructions.txt)
a) This is the sysctl output
sysctl -a | grep hw.physmem
hw.physmem: 3185545216
cat /boot/loader.conf
hw.physmem="0x100000000"
6. Then executed 'kldload vmm'. Got kernel panic with the following trace

I am attaching herewith the text core as well as the info. Can someone tell
me whats happening?
