[Vladimir Vyazmin]

Hi, 

Maybe this will help. I create a note, how remove and install a new installation on RHEVM 3.1: 

Remove / Uninstall RHEVM & VDSM (clear old installation) 

#### Manager: #### 

rhevm-cleanup 
yum -y remove rhevm* vdsm-bootstrap 

rm -rf /var/log/ovirt-engine/engine* 
rm -rf /var/log/ovirt-engine/server* 
rm -rf /tmp/* 

yum clean all 

*** Clean PostgresSQL *** 
psql -U postgres -l 
dropdb -U postgres engine_2012_06_26_10_20_21 
psql -U postgres -l 

#### Host #### 

service vdsmd stop 
# service libvirtd stop 
initctl stop libvirtd 
service libvirtd status 
# initctl status libvirtd 

### yum remove libvirt* vdsm* qemu* sanlock* 
yum -y remove *vdsm* *libvirt* *qemu* *sanlock* jpackage* vdsm-python* 
rm -rf /etc/libvirt/DC-04 
rm -rf /var/lib/libvirt/ 
rm -rf /var/log/vdsm/ 
## rm -rf /var/log/vdsm/vdsm.log* 
## rm -rf /var/log/vdsm/libvirt.log* 
rm -rf /tmp/*

# yum makecache 

### Disconnect all iSCSI sessions: 
iscsiadm -m session 
iscsiadm -m session -u 
iscsiadm -m node
