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

[RamakrishnaDeepak Battu]

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?

address@hidden ~]# lsmod | grep ipmi_devintf

address@hidden ~]# lsmod | grep ipmi_si

address@hidden ~]# uname -s -r

Linux 2.6.32-358.el6.x86_64

I tried installing from yum, and restarting the server , but in vain.

address@hidden ~]# yum install OpenIPMI.x86_64

.....

address@hidden ~]# ls /dev/ipmi0

ls: cannot access /dev/ipmi0: No such file or directory

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.
