CentOS virt - Sep 2007 - kvm guests are not able to restart

hi,
i've got a centos-5 x86_64 kvm-35 host system with one centos-5 i386 and
one x86_64 guests. but none of the guest are able to restart. ie. i
login to the guests and restart it. it start's as normal reboot, but
after the last command (shuting down md device) it's do nothing, but in
virt-manager i see 50% load on the guest. the biggest problem currently
i can't find any way to restart any guest's other then shutdown and use
virt-manager and restart them:-(
what can be a problem? is it a known bug or it's just not working for me?
thanks in advance.

my system:
kernel-2.6.18-8.1.8.el5
kernel-headers-2.6.18-8.1.8.el5
kmod-kvm-35-1.2.6.18_8.1.8.el5
kvm-35-1
libvirt-0.3.2-2
libvirt-python-0.3.2-2
python-virtinst-0.300.0-1
virt-manager-0.5.0-1
virt-top-0.3.2.5-1
virt-viewer-0.0.2-1

is this really true? this means kvm are not usable any real environment
since imho the feature to be able to reboot a server is essential!
