Description Dave Johnson 2011-08-11 15:45:25 UTC

Description of problem:
=======================
Not sure what the requirement is but I was expecting that the matahari host agent shutdown and reboot methods would gracefully shutdown the OS, it doesn't.  It seems to do a immediate halt (and then if reboot, begins to boot)

Version-Release number of selected component (if applicable):
=============================================================
matahari-host-0.4.2-5.el6.x86_64

How reproducible:
=================
100%

Steps to Reproduce:
===================
1.  on a vm, install matahari broker and host
2.  start broker and agent
3.  issue shutdown or reboot to matahari host agent 
4.  see vm, it halts immediately

Comment 2 Andrew Beekhof 2011-08-15 06:17:29 UTC

We use the standard reboot() function (man 2 reboot).
VMs just shut down really quickly.

void
host_os_reboot(void)
{
    reboot(LINUX_REBOOT_CMD_RESTART);
}

void
host_os_shutdown(void)
{
    reboot(LINUX_REBOOT_CMD_HALT);
}

This indicates a "normal" shutdown occurred.

Comment 6 Dave Johnson 2011-08-19 20:32:12 UTC

good 2 go in v0.4.2-7 for both shutdown and reboot methods
