Re: bhyve hangs on going multi user
Hi Sevan, I can now make a guest panic if I assign 4GB or more RAM. What are the memory params you are using in this case ? I've not made any changes on the host such as reserving memory. I'm starting the VM like so: ... -m 4096 Ah - that actually won't work.

Hi Sevan, At the risk of stating the obvious: > pid 17 (stty), uid 0: exited on signal 4 > Illegal instruction > pid 19 (ps), uid 0: exited on signal 4 > Illegal instruction The userland processes launched by /etc/rc are getting a SIGILL but it is not clear why. Could you do some experiments on your end to narrow this down a bit more: - Boot to single user and then execute a variety of commands to figure out whether the problem happens randomly or does is follow a particular executable (for e.g. execute "ps", "stty", "fsck", "find", "ls" etc). - Did this problem start happening only recently? - If you have a different host system does it happen there too? If you have a different virtual machine does it happen there as well? best Neel On Wed, Feb 6, 2013 at 7:55 PM, Sevan / Venture37 wrote: > Hi, > Attempting to start a VM with the following command results in a hang when > the system tries to go multiuser > sudo bhyveload -m 768 -M 8192 -d ./diskdev guest0 && sudo bhyve -c 1 -a -A > -m 768 -M 8192 -I -H -g 0 -s 0:0,hostbridge -s 1:0,virtio-blk,diskdev -S > 31,uart,stdio gues0 > > > /boot/loader.conf > autoboot_delay=5 > kernel="kernel" > > virtio_load="YES" > if_vtnet_load="YES" > virtio_pci_load="YES" > virtio_blk_load="YES" > > # Avoid clock drift > kern.timecounter.hardware="TSC" > kern.timecounter.invariant_tsc="1" > # Tell the guest it is virtualized > #smbios.bios.vendor="Bochs" > smbios.bios.vendor="BHYVE" > > console="userboot" > bootverbose="1" > > > /etc/fstab > /dev/vtbd0s1a / ufs rw 1 1 > > > > > Booting... > GDB: no debug ports present > KDB: debugger backends: ddb > KDB: current backend: ddb > SMAP type=01 base= len=000a > SMAP type=01 base=0010 len=2ff0 > SMAP type=01 base=0001 len=0002 > Table 'APIC' at 0xf0500 > APIC: Found table at 0xf0500APIC: Using the MADT enumerator. > MADT: Found CPU APIC ID 0 ACPI ID 0: enabled > SMP: Added CPU 0 (AP) > Copyright (c) 1992-2013 The FreeBSD Project. > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > The Regents of the University of California.
