Re: [Qemu-devel] QEMU IPMI support

[Corey Minyard]

Ok, done.  It's at https://github.com/cminyard/qemu on github.  There
are two branches at the moment, stable-2.2-ipmi is based on the 2.2
release and will not rebase.  master-ipmi-rebase will rebase on master
as it moves.

I haven't done extensive testing yet, and it has a few experimental
things, like an SMBus IPMI interface and an I2C mux device.  I need to
split all that out at some point.  I also need to rework the ACPI
handling to use the new code to build the ACPI tables.

Copying qemu-devel so that group knows.

Thanks,

Re: [Qemu-devel] QEMU IPMI support

[Longever, Joseph]

Hi Corey,

Thanks so much for the support.  I pulled down the 2.2-ipmi stable snapshot and everything compiled with no issues.

Could you help confirm my configuration?

I ran lanserv with the serial parameter to create the socket that will communicate with the QEMU IPMI device over port 9002:

Host lanserv config:
 addr :: 623

  # Define a serial VM inteface for channel 15 (the system interface) on
  # port 9002, just available to the local system (localhost).
  serial bt localhost 9002 codec VM ipmb 0x20

  # startcmd is what to execute to start a VM associated with the
  # codec above (localhost 9002).  It also starts a console serial port
  # on port 9003 that is also used as the monitor interface.

  startcmd "qemu-system-x86_64 -vnc :1 --enable-kvm -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 -device isa-ipmi,chardev=ipmi0,interface=bt,irq=5 -device e1000,netdev=net0,mac=${VNETMAC} -netdev tap,id=net0 -device ich9-usb-ehci1 -daemonize -serial mon:tcp::9003,server,telnet,nowait -m ${VMEM} -smp ${VSMP} ${STARTCMD_OPTS}"

  # Start startcmd at startup?  Default is false.
  startnow true


But the QEMU VM doesn't find the BMC over the BT channel.  I've tried KCS channel as well,  similar problem.  I also set the serial parameter for channel 15, same.

On VM:
[   10.199536] ipmi message handler version 39.2
[   10.201363] ipmi device interface
[   10.203908] IPMI System Interface driver.

[   10.342602] ipmi_si: Unable to find any System Interface(s)
[   10.344943] IPMI Watchdog: driver initialized

The socket is listening on the host at port 9002 (the LAN port is the default 623):

As a note, that last comment was neither true nor fair.  I apologize for
this statement, and nobody should make disparaging remarks about the
maintainers that work so hard on this.

Can you send your complete configuration file and startup command file? 
I'm guessing you haven't enabled things properly in the startup command
file or in the configuration file, and if you don't do that you won't
get a valid BMC.  It looks like it's connecting, just not working right.

Also, what version of OpenIPMI did you try?  The latest git release is
probably the best.

I just tried it out, BTW, and it worked ok for me.

Hi Corey,

I got it working now.   The port wasn't listening on the correct address when set to localhost but when I set the address to 0.0.0.0 it started listening on 127.0.0.1.

Set serial parameters to:

I'm sure this all works and it's just me... Attached is the config,   I also pasted the text below:

The startcmd starts a QEMU instance which then PXE boots Linux kernel 2.6.34 with IPMI drivers enabled in the kernel:

  startcmd "qemu-system-x86_64 -vnc :1 --enable-kvm -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 -device isa-ipmi,chardev=ipmi0,interface=bt,irq=5 -device e1000,netdev=net0,mac=${VNETMAC} -netdev tap,id=net0 -device ich9-usb-ehci1 -daemonize -serial mon:tcp::9003,server,telnet,nowait -m ${VMEM} -smp ${VSMP} ${STARTCMD_OPTS}"

I'm running the latest version from sourceforge: OpenIPMI-2.0.21.

Can you send your complete configuration file and startup command file? 
I'm guessing you haven't enabled things properly in the startup command file or in the configuration file, and if you don't do that you won't get a valid BMC.  It looks like it's connecting, just not working right.

Also, what version of OpenIPMI did you try?  The latest git release is probably the best.

I just tried it out, BTW, and it worked ok for me.
