Squid? Message-ID: <8bea728a4fb4d5cd804c6aa50cb5e6c8@triadic.us> Content-Type: text/plain; charset=US-ASCII; format=flowed I have a dual host setup working right now. Host 1 runs the engine and is also a node. Host 2 does DB storage and NFS storage. The WebSockets proxy is running on Host1. My question is how do I run this behind a router? I am correct in understanding that the WebSockets proxy acts as the spice access point for all of the nodes in the cluster / datacetner? or does each node host need a direct connection for spice? the .vv file I receive from the management console specifies the engine's private IP address which works fine when inside the ovirt management LAN, but it wont route from WAN obviously. So essentially i guess i need squid to rewrite the served vv file to the public IP and somehow make the ports work correctly, which is difficult considering every time a VM is created it also adds its own spice port, correct? ------------------------------ Message: 3 Date: Sun, 31 May 2015 22:56:40 +0000 From: Soeren Malchow <soeren.malchow@mcon.net> To: "libvirt-users@redhat.com" <libvirt-users@redhat.com>, users <users@ovirt.org> Subject: [ovirt-users] Bug in Snapshot Removing Message-ID: <D1915E46.D966%soeren.malchow@mcon.net> Content-Type: text/plain; charset="us-ascii" Dear all I am not sure if the mail just did not get any attention between all the mails and this time it is also going to the libvirt mailing list.

Taking into account that you can use commodity hardware i would also suggest to split the services, but i would go for at least 3 gluster nodes ? which add up to at least 5 nodes for a HA system. If you want 4 in any case, then my suggestion would be to go for 4 replicas, each node has anything that it needs to run and you can basically use NFS to localhost for the storage which would make the nodes always access the local storage for the VMS, availability wise it makes no difference.
