Intrepid openBIOS developers, Though not new news, thank you for providing an openBIOS that is able to boot solaris in qemu-system-sparc32! While I am able to disk boot (with qcow2 image containing ufs filesystems), but would prefer to serve as much of my guest filesystem from NFS as possible. Netboot allows a 'diskless' system, so that is the most extreme case, but I'm open to other suggestions.
Does OpenBIOS 1.1 (eg the snapshot attached to QEMU GIT HEAD as of last Friday) support boot net:rarp, boot net:dhcp, or any other more manual method of providing the kernel¶meters? I haven't been able to find this in the documentation or code so I imagine it does not.
PS - FWIW this is the command line I am presently using for a 'disk0' boot. Note that the tftp/bootfile do not do anything, but I included them as an example based on the other qemu documentation.
qemu/sparc-softmmu/qemu-system-sparc \ -net nic,macaddr=00:03:BA:04:A5:AD -net user,hostfwd=tcp::8023-:23,hostfwd=tcp::5911-:5911,tftp=/tftpboot,bootfile=inetboot.sun4m \ -hda sol8_36G.disk.install \ -nographic -serial telnet:0.0.0.0:3000 http://0.0.0.0:3000/,server \ -m 256
PPS Mark Cave-Ayland, it appears you're active on this list. Thanks again for your help (now years ago!) fixing the MUTEX_HELD & related problems in 2.6.... the current GIT still runs clean. I have not really worked with QEMU since ~2.6, around that time I picked up a SunBlade 1000, which is supported by the old kernel I need, and is able to run the (mostly CC compile) workloads an order of magnitude faster. QEMU remains interesting for applications requiring less performance, e.g. lmgrd license server.
Hi Joe,
Glad to hear that everything is still working well for you! Unfortunately OpenBIOS doesn't have a TCP/IP stack (and I don't have any immediate plans to do this) so you'll need to find another solution.
Probably the easiest one I can think of right now is to get hold of a real SS5 ROM from the internet and pass that into QEMU via the command line parameter -bios /patch/to/SS5.bin. You can then use some expect scripting or similar in -nographic mode to enter the relevant boot command automatically into the PROM on startup.
ATB,
Mark.
