It on= ly works for guests that support the 'bvmdebug' driver (which currently only exists for FreeBSD AFAIK), and similar to 'bmconsole' mostly existed as a simple device model before bhyve supported UARTs. A more portable approach= to connect to a gdb stub in a guest OS now is to use a UART to do so (e.g. I w= ire up /dev/nmdm2B to com2 for my guests so that gdb can connect to /dev/nmdm2A to connect to a gdb stub on com2 in the guest which potenti= ally works with multiple OSes). -G is more like qemu's -g. I'd be tempted to deprecate bvmconsole and bvmdebug, but I'd defer to Peter= on that. I realize we'd need to document -G better regardless, but if we want= to move forward with deprecating bvmdebug it might affect the language we use = to describe -g vs -G. --=20 You are receiving this mail because: You are the assignee for the bug.=
