Re: [ovirt-users] oVirt 3.5 & NAT

Well, in fact have got something to work now! Left ovirtmgmt and em1 alone but ran: $ ovs-vsctl add-br ovsbr0 $ ip link add name veth0 type veth peer name veth1 $ brctl addif ovirtmgmt veth0 $ ovs-vsctl add-port ovsbr veth1 $ ip add add XXX.XXX.XXX.XXX/29 dev veth1 $ ip link set veth0 up && ip link set veth1 up and now veth1 is responding as-well as veth0. ovs-vsctl show 08554d11-3ba7-4303-b9d5-6a09f23c9057 Bridge "ovsbr0" Port "veth1" Interface "veth1" Port "ovsbr0" Interface "ovsbr0" type: internal so what I think should do now is create a custom parameter on the Engine Manager that allows one to define an OVS bridge name and VLAN so when a virtual guest is created it can be assigned to the new bridge; with the use of a custom hook.

So at that point you have network running. If you then try to add that to the OVS stack your networking stop :( I tried to add it as a port using ovs-vsctl add-port ovsbr0 ovirtmgmt which is accepted but then networking stops. As soon as I remove again networking comes back to life. There does not seem to be a way to have two co-existing bridges :( Thanks, Phil ----- Original Message ----- From: "Antoni Segura Puimedon" <asegurap(a)redhat.com> To: "Phil Daws" <uxbod(a)splatnix.net> Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org Sent: Monday, 27 October, 2014 12:13:30 PM Subject: Re: [ovirt-users] oVirt 3.5 & NAT ----- Original Message ----- > From: "Phil Daws" <uxbod(a)splatnix.net> > To: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > Sent: Monday, October 27, 2014 11:41:56 AM > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > Hi Antoni: > > Yes, prior to the reboot it did work okay.

You could just make a hook script that runs an after_network_setup hook that does the ovs-vsctl for you ;-) Here you can see the presentation I gave last February at devconf about extending with configurators and hooks. http://blog.antoni.me/devconf14/#/8/1 I linked directly to a before_network_setup hook sample, because it works just like the after_network_setup hook. Instead of logging to systemd, just add that if 'remove' is not in data and network == 'ovirtmgmt', it adds the network bridge to the vswitch with python's subprocess.call or subprocess.check_output. You can send it if you want me to take a look ;-) PS: It is possible to write the hooks in bash, c, perl, etc. But we only have the convenience read_json methods and such for python. If you wanted to, you could have a simple bash hook that just checked if there was an ovirtmgmt bridge and it would add it doing ovs-vsctl in the before_vdsm_start hooking point. That would have the drawback that changing the ovirtmgmt bridge with oVirt UI would leave it disconnected again. > > Thanks, Phil > > ----- Original Message ----- > From: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > To: "Phil Daws" <uxbod(a)splatnix.net> > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > Sent: Monday, 27 October, 2014 9:56:38 AM > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > ----- Original Message ----- > > From: "Phil Daws" <uxbod(a)splatnix.net> > > To: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > > Sent: Monday, October 27, 2014 10:37:18 AM > > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > That is what I tried but oVirt appears to overwrite the bridge information > > on > > boot :( Thanks, Phil > > But before rebooting, does it work as you intended?

all-in-one updated from 3.4.4 to 3.5.0 ok with reinstall of host part
by Gianluca Cecchi 27 Oct '14

27 Oct '14

On a fedora 19 system where I had 3.4.4 all-in-one, I was able to upgrade to 3.5. vdsm part had problems I was able to solve reinstalling host from the webadmin gui Steps were: - follow instructions for engine part --> ok - verify connectivity of engine via new webadmin - put host into maintenance - stop vdsmd service - yum update vdsm part and all other packages related to ovirt When trying to start vdsm again I got [root@tekkaman vdsm]# systemctl status vdsmd vdsmd.service - Virtual Desktop Server Manager Loaded: loaded (/usr/lib/systemd/system/vdsmd.service; enabled) Active: failed (Result: start-limit) since Sat 2014-10-25 16:01:29 CEST; 2min 54s ago Process: 14448 ExecStartPre=/usr/libexec/vdsm/vdsmd_init_common.sh --pre-start (code=exited, status=1/FAILURE) Oct 25 16:01:29 tekkaman.localdomain.local systemd[1]: Failed to start Virtual Desktop Server Manager.

Nevertheless a host reinstall from webadmin gui seemed to fix the problem and after that it was able to start vdsm ad host part. I was also able to upgrade DC/Cluster from 3.4 to 3.5 version. Now that I'm on 3.5 next days I'll try to pass from F19 to F20... we'll see Gianluca

oVirt 3.5 & NAT
by Phil Daws 27 Oct '14

27 Oct '14

Hello All! Am really enjoying experimenting with oVirt but have come across a question; how does one enable NAT for a VM ? Would like my guests to be able to update their software by bridging the host public IP. I could not see anything in the WUI to allow this ? Thanks, Phil

Deleting large snapshots blocks the whole cluster

Problem installing hosted engine on CentOS 7 host
by Justin Clacherty 27 Oct '14

27 Oct '14

Hi, I'm just trying to set up ovirt 3.5 for testing and am unable to get hosted engine installed. The problem appears to be something to do with multipath iscsi setup. I run 'hosted-engine --deploy' and answer all the questions. See the config preview below. --== CONFIGURATION PREVIEW ==-- Engine FQDN : ovirt.domain.local Bridge name : ovirtmgmt SSH daemon port : 22 Firewall manager : iptables Gateway address : 192.168.42.254 Host name for web application : hosted_engine iSCSI Target Name : iqn.2014-10.storage.domain.san0:iscsi0 iSCSI Portal port : 3260 Host ID : 1 iSCSI LUN ID : 0 Image size GB : 25 iSCSI Portal IP Address : 10.50.0.200 iSCSI Portal user : myuser Console type : vnc Memory size MB : 4096 MAC address : 00:16:3e:23:b4:c2 Boot type : cdrom Number of CPUs : 2 ISO image (for cdrom boot) : /tmp/CentOS-7.0-1406-x86_64-DVD.iso CPU Type : model_Nehalem At the iscsi target question it shows both target names (for each of the multipath options) but you only seem to be able to choose one. After confirming the settings above I get the following. [ INFO ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf' [ INFO ] Stage: Transaction setup [ INFO ] Stage: Misc configuration [ INFO ] Stage: Package installation [ INFO ] Stage: Misc configuration [ INFO ] Configuring libvirt [ INFO ] Configuring VDSM [ INFO ] Starting vdsmd [ INFO ] Waiting for VDSM hardware info [ INFO ] Creating Volume Group [ ERROR ] Failed to execute stage 'Misc configuration': Failed to initialize physical device: ("['/dev/mapper/36001405fbaac4f30dd647b083c6a0116']",) [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf' [ INFO ] Answer file '/etc/ovirt-hosted-engine/answers.conf' has been updated [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination The /dev/mapper leads me to believe it's a multipath issue. I noticed this Bugzilla entry when looking into the issue so it appears at least one other person is experiencing the same issue. https://bugzilla.redhat.com/show_bug.cgi?id=1154353 Cheers, Justin.

Import FC Storage as iSCSI
by Raul Laansoo 27 Oct '14

27 Oct '14

Hello. I have created an FC Storage Domain and made snapshots of all LUNs on the SAN. Now I want to use those snapshots on another Data Center over iSCSI connection to test recovery. I can import the domain, but the domains Storage Type is FC and I can't attach it to host. Is it possible to change domain type to iSCSI or some other way to import storage domain. Thank you. Raul
