Re: [Qemu-devel] QEMU IPMI support

[Longever, Joseph]

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:
serial 15 0.0.0.0 9002 codec VM ipmb 0x20

[   10.025336] ipmi message handler version 39.2
[   10.026097] ipmi device interface
[   10.027495] IPMI System Interface driver.
[   10.028333] ipmi_si: Trying SMBIOS-specified bt state machine at i/o address 
0xe4, slave address 0x20, irq 5

[   10.045493]   Using irq 5
[   10.100474] IPMI BT: req2rsp=10 secs retries=0

[   10.245082] IPMI Watchdog: driver initialized

Thanks,
  Joel

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.
