[Qemu-devel] Cant make the IPMI simulator work, help needed.

[-- Attachment #1: Type: text/plain, Size: 1835 bytes --]

Hi,

I am trying to simulate the IPMI simulator for test purposes  but was
failing somehow..
I see lot of help being given in this forum , especially Corey Minyard.
Thank you.
I am new to IPMI and QEMU, but followed the threads and was able to fix up
to some point. Right now struck and not able to figure out .So reaching for
you guys help.

I compiled and installed  stable-2.2-ipmi Qemu branch, and new version of
OpenIPMI.
I am using the cirros image to boot up using the Qemu.

My startcmd is as follows:

/usr/local/bin/qemu-system-x86_64 --enable-kvm  -nographic -net
nic,model=e1000,macaddr=52:54:00:12:34:59 -net
user,hostfwd=tcp::5555-10.0.2.15:22 -chardev
socket,id=ipmi0,host=localhost,port=9002,reconnect=10 -device
isa-ipmi,chardev=ipmi0,interface=bt,irq=5 -serial
mon:tcp::9003,server,telnet,nowait -initrd
/opt/cirros/cirros-0.3.4-x86_64-initramfs -kernel
/opt/cirros/cirros-0.3.4-x86_64-kernel --append 'root=/dev/hda
console=ttyS0,115200'

When ran Qemu command alone on the console get this error:
qemu-system-x86_64: Unable to connect character device ipmi0: Error
connecting to socket: Connection refused

My BMC and lan.conf are
https://gist.github.com/bot11/5d33a14a1cba442b5ef2
https://gist.github.com/bot11/3c385eea081609a8a7f4

Once I ran the ipmi_sim command, I can see the bmc variables read from the
emu file, but I dont see the qemu instance booted up.
And when I ran the ipmitool , I am getting the following errors:

[root@localhost~]# ipmitool -I lanplus -v  -H 127.0.0.1 -p 9002 -U ipmiusr
power status
              Password:
Get Auth Capabilities error
Get Auth Capabilities error
Error issuing Get Channel Authentication Capabilies request
Error: Unable to establish IPMI v2 / RMCP+ session
Unable to get Chassis Power Status
----


This is where I am struck. Please suggest.

Thanks,
Ramakrishna.

This question is probably best destined for the openipmi mailing list,
not qemu, so I'll add that to the CC.

This work is still not completely there, so it will be changing, but it
should work as is.

What happens when you run this by hand directly from the command line?

You have the IPMI port set to 623 in the lan.conf config.  You have the
VM interface on port 9002.  So you should use 623.

Thank you Corey.

I haven't noticed the port 623, I changed it.

If I ran this command alone:
/usr/local/bin/qemu-system-x86_64 --enable-kvm  -nographic -net
nic,model=e1000,macaddr=52:54:00:12:34:59 -net
user,hostfwd=tcp::5555-10.0.2.15:22 -chardev
socket,id=ipmi0,host=localhost,port=623,reconnect=10 -device
isa-ipmi,chardev=ipmi0,interface=bt,irq=5
-serial mon:tcp::9003,server,telnet,nowait -initrd
/opt/cirros/cirros-0.3.4-x86_64-initramfs -kernel
/opt/cirros/cirros-0.3.4-x86_64-kernel --append 'root=/dev/hda
console=ttyS0,115200'

I am getting the following error:
qemu-system-x86_64: Unable to connect character device ipmi0: Error
connecting to socket: Connection refused


I dont see the IPMI momdules installed on the server I was using , is that
the cause?
[root@redhat2 ~]# lsmod | grep ipmi_devintf
[root@redhat2 ~]# lsmod | grep ipmi_si
[root@redhat2 ~]# uname -s -r
Linux 2.6.32-358.el6.x86_64

I tried installing from yum, and restarting the server , but in vain.
[root@redhat2 ~]# yum install OpenIPMI.x86_64
.....
[root@redhat2 ~]# ls /dev/ipmi0
ls: cannot access /dev/ipmi0: No such file or directory


Thanks,
Ramakrishna.

That was the wrong thing to change.  The port there is the connection to
OpenIPMI's VM interface, which is 9002.  623 is the port you use for
ipmitool.

Set the port back to 9002 in the command line above, run ipmi_sim, leave
ipmi_sim running, and run qemu from the command line.  That way it has
something to connect to.

Also, what branch in the qemu ipmi repository are you using?  The 2.3
one may have an issue.  The 2.2 one should work ok.

No, that's irrelevant for this.
