HI Pearl and Zhou, Thanks for the reply. virbr0 is not a problem now.
But I've set the ca.plugin.root.auth.strictness to false and restarted the mgt server, the host still shows ssl handshake error. Also When I tried the deployDatacenter.py, it shows "=== TestClient Creation Failed===" and the mgt server logs ``` ERROR [c.c.u.n.Link] (AgentManager-SSLHandshakeHandler-1:null) (logid:) SSL error caught during unwrap data: Unrecognized SSL message, plaintext connection?, for local address=/172.20.0.1:8250, remote address=/172.20.0.1:54128. The client may have inva lid ca-certificates. ``` Thanks, Junxuan Wu On Mon, 28 Jun 2021 at 23:53, Pearl d'Silva <pearl.dsi...@shapeblue.com> wrote: > Hi Junxuan, > > To address the issue wrt SSL, you may try setting the following global > setting - "ca.plugin.root.auth.strictness" to false and restart your > management server. > > Thanks, > Pearl > ________________________________ > From: Wei ZHOU <ustcweiz...@gmail.com> > Sent: Saturday, June 26, 2021 2:31 PM > To: dev@cloudstack.apache.org <dev@cloudstack.apache.org> > Subject: Re: [GSoC] Issues occured on kvm host: SSL handshake Error > > Hi, > > I can answer your last question about the virbr0. > > In the past we had some issues if vm on another network also uses IP in > 192.168.122.0/24.
