Asus ASMB4 KVM – How to restart from bash command line

I'm managing to do the same thing with these BMC (SuperMicro SMC-0001) on two SuperMicro servers. I didn't try to setup the console redirection yet because I ran onto a "privilege level" problem on one of the two BMC :

# ipmitool user list 1
ID  Name         Callin  Link Auth  IPMI Msg   Channel Priv Limit
1                true    false      true       NO ACCESS
2   ADMIN        true    false      true       USER
Get User Access command failed (channel 1, user 3): Parameter out of range

The user 2 (ADMIN) should have administrator privileges, but the common way to fix it doesn't work :

# ipmitool user priv 2 1 4
Set Privilege Level command failed (user 2): Request data field length limit exceeded

Then I used "tshark" and "IPMIView" on the other server to "watch" the raw command that IPMIView send when changing a user privilege. Here you go :

# ipmitool raw 0x06 0x43 90 02 04

( 02 = UserID , 04 = Administrator privilege )

You can also reset the password for this user (2)

# ipmitool user set password 2 ADMIN

And to connect from an other host you'll have to use a specific driver

# ipmitool -o supermicro -H my.ipmi.host.ip -U ADMIN -P ADMIN mc info

Voila, 'hope it helps

On the host:

Look at your process list. A KVM machine started with VT-x acceleration will contain the command line option -machine accel=kvm (possibly along with other related machine options).

$ ps ax | grep accel=kvm
14912 ?        Sl    90:09 /usr/bin/qemu-system-x86_64 -machine accel=kvm -name Windows2012R2 ...........
