I have a VM which acts as an oVirt host with VDSM installed. I use it for testing without connecting it to Engine.

Recently VDSM fails to come up and I see this error:
Sep 26 17:58:18 localhost libvirtd: 2018-09-26 14:58:18.978+0000: 12176: error : virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired

Any hint on how to generate or fetch a new certificate without the help of Engine?
