[-- Attachment #1 --] Hi I have hit another road block while trying to run the guest using bhyve. These are the steps I followed. I have used http://people.freebsd.org/~neel/bhyve/bhyve_instructions.txt as the reference for preparing and running guest. 1. As posted in my previous e-mail, I installed FreeBSD 9 and then checked out /projects/bhyve and installed the world and kernel from that. Later I am going to use the same kernel, (built from /projects/bhyve, thats used to update from Freebsd-9 to latest in /projects/bhyve) for the guest in step 9. Also the virtio kernel modules I use in step 9 are from the ones built from /projects/bhyve. 2. I have 8gb ram and I have set aside 4gb for the vms. sysctl -a | grep hw.physmem hw.physmem: 3185541120 3. I have successfully performed upto step 7 in http://people.freebsd.org/~neel/bhyve/bhyve_instructions.txt. 4. Skipped step 8, as I plan to use virtio built from the latest code from /projects/bhyve (As part of updating the host freebsd to the latest source in /projects/bhyve, as mentioned above, I also made the virtio modules.) 5. Created vm1 directory in /usr/share and created all its sub-directories and their contents. I copied only the mdroot file from http://people.freebsd.org/~neel/bhyve/vm1.tar.gz. (remember that I copied /boot/kernel (i.e. host kernel) as the guest kernel) 6. Then cd to /usr/share/vm1 and execute './vmrun.sh vm1'. After the freebsd boot loader prompy comes up for the guest, after I hit enter, I get segfaulted with core. I am attaching herewith the backtrace of the core. Also I am pasting below the loader.conf file witihn /usr/share/vm1/boot. Any idea what is happening? Also is there any easy way to configure and run the guest, after building the host kernel with bhyve hypervisor? loader.conf ------------------- kernel="/kernel" virtio_load="YES" if_vtnet_load="YES" virtio_pci_load="YES" virtio_blk_load="YES" kern.hz="100" hw.pci.enable_msix="0" hw.pci.honor_msi_blacklist="0" bootverbose="1" mfsroot_load="YES" mfsroot_type="mfs_root" mfsroot_name="mdroot" Thanks On Wed, Jul 18, 2012 at 11:17 AM, sree.openwrk <sree.openwrk@gmail.com>wrote: > Hey Neel > Thanks for the immediate reply. > I found that the BIOS did not have vm-x and vt-d enabled and luckily > enabling them fixed the issue. > Now I am able to load the vmm module and its not throwing any error as of > now. > > Thanks > > > On Tue, Jul 17, 2012 at 10:07 PM, Neel Natu <neelnatu@gmail.com> wrote: > >> Hi, >> >> On Tue, Jul 17, 2012 at 9:12 PM, s vas <sree.openwrk@gmail.com> wrote: >> > Hi >> > I have a kernel panic when loading bhyve hypervisor kernel module. >> > These are the steps I followed >> > 1.
