I've never tried setting multiple IPs on my ovirtmgmt bridge on the host. But you shouldn't have to do that. It's a bridge, after all, so all systems that sit on that bridge (which include your VMs) will be equivalent. In my case I have an external router that gets used for both of my networks (I have a 192.168 network as well as a full class-C but they share physical infrastructure). So my host only has a 192.168 address, my engine is on the class-C, and they talk to each other over the standard network. In your case it *SOUNDS* like you need to set up an internal router for the /29. The way I would do it would be: /32 /32 /29bridge +--- host (/29) ISP-Router --- internal-router --+--- VM (/29) +--- VM (/29) I don't know if you can actually do this. If not, your other option would be: /32 bridge +--- host (/32) router ---+--- VM Router (/29) (pfsense?) +--- VM (/29) This may not work for you, either, depending. WORST case you may need to manually configure a second IP on the ovirtmgmt bridge on your host: /32 bridge +--- host (/32 + /29) router ---+--- VM (/29) +--- VM (/29) I would do this by manually creating the config file on your host: /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt:0 > Thanks > Mark -derek -- Derek Atkins 617-623-3745 de...@ihtfp.com www.ihtfp.com Computer and Internet Security Consultant ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] Self hosted single server network requirements
Follow-up - I finally discovered the source of my networking troubles. The provider (Hetzner) configures the primary IP in a somewhat odd manner for Cent OS 7.2. For instance, here is /etc/sysconfig/network-scripts/ifcfg-eth0 (lightly edited) DEVICE=eth0 ONBOOT=yes BOOTPROTO=none IPADDR=A.B.4.9 NETMASK=255.255.255.255 SCOPE="peer A.B.4.1" And /etc/sysconfig/network-scripts/route-eth0 ADDRESS0=0.0.0.0 NETMASK0=0.0.0.0 GATEWAY0=A.B.4.1 The key thing is the SCOPE line. This creates a private link between the server's IP and the gw IP. The server's IP address no longer has a netmask, which is now specified on the gw IP. The odd network config appears to confuse the hosted-engine deploy process because it was unable to configure the ovirtmgmt bridge in a working manner. Once I delete route-eth0 and changed ifcfg-eth0 to a more typical configuration all started working. Now I just need to figure out how to configure the /29 for the VMs. Thanks Mark - Derek Atkins wrote: > Hi, > > On Mon, November 21, 2016 4:30 pm, Mark Steckel wrote: > > > [snip] > >> >> > Advice so far seems to be: > >> >> > * Use 'screen' when deploying.

I wound up using a script I found to clean the host and re-install it all. Of course the cleanup process let the firewall in a state where it blocked all traffic (including SSH), but I figured that part out on the 2nd try so added it back into my script for the 3rd. ;) The other difference is that I had already created a bond0 interface which was my default (with a non-NM-controlled static network).

My recommendation is that you just set up non-NM-controlled static network using your public /32. Then the hosted-engine --deploy process should take that config and apply it to ovirtmgmt bridge. At least, that's what happened for me when I did it. I don't think you need to set up the ovirtmgmt bridge manually.

Re: [ovirt-users] Self hosted single server network requirements
Thanks all who have responded so far. Advice so far seems to be: * Use 'screen' when deploying. Easy * Don't use/disable Network-Manager. Easy * Preconfigure the ovirtmgmt bridge. I've got questions... The server has a public /32 as the primary IP, and a public /29 which will be used for the VMs. Besides creating the ovirtmgmt bridge is there anything specific for how I should configure it?

[ovirt-users] Self hosted single server network requirements
Hi folks, I'm a complete OVirt newbie trying to set up a self hosted, single server and looking for some pointers to get going... (While new to OVirt, I'm long time sysadmin so not totally clueless.) The server I'm using has a 4-core CPU, 64 GB of ram, and a pair of 500 GB SSDs set up with RAID 1 and running CentOS 7.2. (I do not have physical access to the server but can get KVM access when required.) The goal is to set up this server as a self hosted, single server OVirt platform. Nothing mission critical, just want to be able to spin up VMs when needed and destroy them afterwards. Trying to use OVirt 4.0.4 (now 4.0.5). I've read some docs for setting this up including those just below as well as a bunch of googling and reading through the list archive. http://www.ovirt.org/documentation/how-to/hosted-engine/ http://www.ovirt.org/develop/release-management/features/heapplianceflow/ http://www.ovirt.org/blog/2016/08/up-and-running-with-ovirt-4-0-and-gluster-storage/ Every time I execute "hosted-engine --deploy" the process "hangs" when it migrates the public IP address to a virtual nic interface. And in this case, by "hang" I mean that I lose the connection to the server. I have no idea if the process finishes or errors out. So obviously I'm doing something wrong. I suspect that I need to take care of some network requirement before starting. However, I can't find anything in the docs of how to prep the server network environment before running "hosted-engine --deploy". Should probably also mention that some, if not all of the VMs will need a public IP address. The physical server has a /29 to get started. Any pointers would be greatly appreciated.
