Looks like use_virsh=0 has no effect.

--
[root at cvtst3 ~]# export OCF_RESKEY_name="guest1" ; OCF_RESKEY_path="/vms_c"
; OCF_RESKEY_use_virsh=0
[root at cvtst3 ~]# set -x
++ printf '\033]0;%s@%s:%s\007' root cvtst3 '~'
[root at cvtst3 ~]# /usr/share/cluster/vm.sh start
+ /usr/share/cluster/vm.sh start
Hypervisor: xen
Management tool: virsh
Hypervisor URI: xen:///
Migration URI format: xenmigr://target_host/
Virtual machine guest1 is error: failed to get domain 'guest1'
error: Domain not found: xenUnifiedDomainLookupByName

<debug>  virsh -c xen:/// start guest1
error: failed to get domain 'guest1'
error: Domain not found: xenUnifiedDomainLookupByName

++ printf '\033]0;%s@%s:%s\007' root cvtst3 '~'
[root at cvtst3 ~]# set +x
+ set +x
