- add comments which describe exit status codes of /usr/sbin/bhyve
- move bhyvectl --destroy outside of the while loop
- Use "file -s" so that we can run vmrun.sh against special devces such as
/dev/md memory files systems or zvols
Sync vmrun.sh with HEAD:
- Add -e option to vmrun.sh passed to bhyveload(8) to set loader
environment variables.
- Stop passing unused -I option to bhyve(8).
- Reformat the usage to fit in 80 colums and other cleanups.
- Add -C option to specify the console device.
- Add -H option to pass a host path to bhyveload(8).
- Support for multiple disk and tap devices.
The latest versoin of file/libmagic identifes a filesystem image
is identified as "DOS/MBR boot sector" as opposed to "x86 boot sector".
This trips up vmrun.sh when using the new file(1) and makes it want to boot
into the installer instead.
Fix this by just looking for "boot sector" instead.
Add support for PCI-to-ISA LPC bridge emulation. If the LPC bus is attached
to a virtual machine then we implicitly create COM1 and COM2 ISA devices.
Prior to this change the only way of attaching a COM port to the virtual
machine was by presenting it as a PCI device that is mapped at the legacy
I/O address 0x3F8 or 0x2F8.
There were some issues with the original approach:
- It did not work at all with UEFI because UEFI will reprogram the PCI device
BARs and remap the COM1/COM2 ports at non-legacy addresses.
- OpenBSD GENERIC kernel does not create a /dev/console because it expects
the uart device at the legacy 0x3F8/0x2F8 address to be an ISA device.
- It was functional with a FreeBSD guest but caused the console to appear
on /dev/ttyu2 which was not intuitive.
The uart emulation is now independent of the bus on which it resides. Thus it
is possible to have uart devices on the PCI bus in addition to the legacy
COM1/COM2 devices behind the LPC bus.
The command line option to attach ISA COM1/COM2 ports to a virtual machine is
"-s <bus>,lpc -l com1,stdio".
The command line option to create a PCI-attached uart device is:
"-s <bus>,uart[,stdio]"
The command line option to create PCI-attached COM1/COM2 device is:
"-S <bus>,uart[,stdio]". This style of creating COM ports is deprecated.
