[ovirt-users] Change Hosted Engine VM MAC address

Good morning, colleagues! Due some network issues I need to change HostedEngine VM MAC address. The additional diffeculty is unaccessebility of the HE Web-interface via the network (the cause of - those network issues -)). Is there any way to change the HE vNIC's MAC using command line (on the host where HE VM works or on the HE VM)? Thanks in advance, Sergei.
