Comment 3 Lawrence Lim 2010-06-24 08:01:18 UTC 
What about other moe of shutdown?
Comment 4 Jianjiao Sun 2010-06-24 08:28:01 UTC 
yeah!

#shutdown -h now 
works well .

But I think there are a lot of people like "#halt",beacuse It is convinet to use.

rhel3u9 halt

I can reproduced this issue.

1. Intall rhel3u9 or rhel4u8 guest
2. Log in guest and execute command
   # halt
3. The guest cannot be able to fully shutdown.

Using 'shutdown -h now' can workaround this issue. I captured a screenshot.
Comment 7 Daniel Berrangé 2010-06-25 14:00:33 UTC 
I don't believe this is a bug. The 'halt' command is only intended to halt the operating system, not power off the machine. The 'poweroff' command should be used if you want the guest to actually power off the machine.

Shutdown -h is equivalent to poweroff in normal configs.

Please re-test with the 'poweroff' command.
Comment 8 Nan Zhang 2010-06-25 14:26:16 UTC 
Yes, the guest can be shutdown with the 'poweroff' command, so it's not a bug. Close it.
