Probably, but you would need to set the websocket proxy which is part of installation steps for engine as well (I believe).

> 2. Is the spice-proxy architecture diagram like: browser --------- squid > proxy - spice-proxy ---------------------- VM Browser plugin spice-xpi invokes start of Spice client (virt-viewer) which makes CONNECT to Host machine (where the VM is hosted) through the HTTP proxy (in your case squid). Client machine ---> Squid ---> Host (where the VM is hosted). > 3. I didn't explicitly install any certs for the squid proxy. Is it > automatically taken care of? No, no authentication to Squid is supported with Spice now. So If It is publicly visible proxy It's important to set careful proxy rules. > > > References: > > http://www.ovirt.org/Console_Client_Resources > > http://www.ovirt.org/Features/Spice_Proxy > > https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Vir... > > > Thanks. > > David > > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users
