[Users] How do Networks and Vlan-tagging work in oVirt ?
by Matt . 14 Feb '13

14 Feb '13

I'm struggeling setting up my network in oVirt at the moment as I would like to seperate specific VM's from other devices/clients in my network. I have decent setup switching network using Vlans, this is also the fact for ovirt and the storage nodes where teh ports are seperated between storage and management. Because I want to manage which client can acces which VM I need Vlan tagging. The question is where are we going to do this, on the VM itself or on the network I attach the VM's Nic to. Because of the lacking documentation at this point it's not clear, so I would like to figure out and maybe change the wiki there. I also cannot understand why I can set an IP to a network and only the subnet where I also can set DHCP which puts also the gateway. I'm not able to set None or DHCP and can only add a network with IP, but what IP and why ? Or just a 192.16.x.0 with a 255.255.255.0 subnet ? I hope someone can clear this a little bit more out. Thanks!

[Users] HA wirh oVirt
by Alexandre Santos 13 Feb '13

Hi all, I've been asked for a HA solution and I've been testing oVirt with a NFS NAS and 2 hosts where I run 2 VMs that have a balancer at their front, each on a different host. Now I'm thinking on the possibility of a host malfunction and my question is: is there automatic migration of the VMs that are running on this host to the other host? Sorry if it is a silly question :-) Alex

Alex [DF] Power management needed so the engine will be able to fence the malfunctioned host, and only then the VM will auto-migrate. This ensures the VM will not run twice on different hosts while corrupting the disks.

[Users] Fedora 17 firefox not optimal for 3.2 beta
by Gianluca Cecchi 13 Feb '13

13 Feb '13

Hello, connecting to ovirt 3.2 beta from F17 with firefox-18.0-1.fc17.x86_64 I receive This Browser version isn't optimal for displaying the application graphics (refer to Documentation for details) How is the check made to show or not the warning? What is the current status of supported browsers? I remember someone posting a page with browser support but I'm unable to find it right now... I remember also on December the thread [Users] Using the chrome/chromium browser with oVirt Did it go ahead with chrome spice-xpi patches applied and so now chrome usable in f17 / f18 (btw on my f17 I have google-chrome-stable-24.0.1312.69-180721.x86_64 if needed for testing)? Thanks, Gianluca

I used this command vncviewer 192.168.1.102 ::5902 note the space between ip and ::5902 This way it seems the ip is totally ignored without returning any syntax error and so it implicitly tries localhost So clearly any client that tries to connect fails (if it is not a vnc server on that port itself, obviously...) And carefully reading the man page helps too: vncviewer [options] [host][::port] Instead if for example I install vncviewer and run the same command from the node itself it succeeds.... ;-) The correct command without the space vncviewer 192.168.1.102::5902 completes correctly I understood this noticing the "127.0.0.1" when prepending the "strace" command from the client and the wrong syntax: open("/etc/host.conf", O_RDONLY|O_CLOEXEC) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=9, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fa457040000 read(3, "multi on\n", 4096) = 9 read(3, "", 4096) = 0 close(3) = 0 munmap(0x7fa457040000, 4096) = 0 futex(0x38785b5ae0, FUTEX_WAKE_PRIVATE, 2147483647) = 0 open("/etc/hosts", O_RDONLY|O_CLOEXEC) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=250, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fa457040000 read(3, "127.0.0.1 localhost localhost."..., 4096) = 250 read(3, "", 4096) = 0 close(3) = 0 munmap(0x7fa457040000, 4096) = 0 socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 connect(3, {sa_family=AF_INET, sin_port=htons(5902), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ECONNREFUSED (Connection refused) close(3) = 0 ALso because connecting from the node itself with the wronh syntax I got the ESTABLISHED on localhost ip.....

(Name of ISO Domain is cloud12) 4. Uploaded ISO using the command (engine-iso-uploader upload -i cloud12 Centos_6.3_64bit.iso) 5. Adding HOST. 6. Create VM (New Server & Desktop) with VNC console. But when I view the VNC console..It shows nothing but a Black Window. And I see none remarkable error @ tail -f /var/log/ovirt/ovirt-engine/engine.log Only the following things: * "No one is waiting for resource 'Storage.fce396f2-72cb-11e2-acc2-000c29a7b590"* In fact I have been hanging in this place for 3 to 4 days. It would be appreciable if you please help me out from this stuck situation.

Hi, Just a quick question. I have PXE boot setup correctly now and like to do an unattended install. In the rhev-m documentation I see the parameter "rhevm_admin_password" . Is this engine_admin_password in ovirt? -- Regards, Jorick Astrego Netbulae B.V. Site: http://www.netbulae.eu
