I install fedora16 (minimal install) in vm

if I use engine-setup after "yum update" with

#uname -a
#Linux ovirt-m 3.1.6-1.fc16.x86_64 #1 SMP Wed Dec 21 22:41:17 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

there is an error in step  "Creating CA..."

./SignReq.sh: line 79: /var/lock/ovirt-engine/.openssl.exclusivelock: No such file or directory
file certs/engine.cer does not exist!
2011-12-26 19:02:47::DEBUG::common_utils::206::root:: retcode = 1

  File "/usr/share/ovirt-engine/scripts/common_utils.py", line 209, in execCmd
    raise Exception(msg)
Exception: Return Code is not zero

but on fedora16 without update  this step is OK
