Hi,
I'm new to OpenBSD and I'm trying a simple setup where a VMM guest has
access to the network via tap and bridge. The host uses a wired connection
and gets its network address with DHCP.
Here's my /etc/vm.conf:
switch "vms_switch" {
interface bridge0
add bge0
}
vm "vm.test" {
memory 1G
boot /home/fstephany/bsd.rd
disk /var/vms/fstephany/vmtest-disk.img
owner fstephany
interface tap {
switch "vms_switch"
}
disable
}
I've stopped vmd with #rcctl stop vmd
and started it manually:
# vmd -dvv
startup
/etc/vm.conf:4: switch "vms_switch" registered
/etc/vm.conf:15: vm "vm.test" registered (disabled)
vm_priv_brconfig: interface bridge0 description switch1-vms_switch
vm_priv_brconfig: interface bridge0 add bge0
vmd_configure: not creating vm vm.test (disabled)
vm_opentty: vm vm.test tty /dev/ttyp1 uid 0 gid 4 mode 620
vm_priv_ifconfig: interface tap0 description vm1-if0-vm.test
vm_priv_ifconfig: interface bridge0 add tap0

Here's what happens when the installer tries to get a network address:
# vmctl status

# vmctl start vm.test -c
