As I did read here<http://community.gluster.org/q/can-i-use-glusterfs-as-an= -alternative-network-storage-backing-for-vm-hosting/> GlusterFS isn't actua= lly the best solution for big VM images? (by the way what means big here?) Does anybody here can share his experience with using GlusterFS, how many VMs are running and what is the expected IO per second for a VM ? (I know this can differ enormously) We have about Perhaps somebody here already uses 3.3 (with self-healing) ? I'm pretty looking forward to GlusterFS 3.4, as the new features seem to be= "made" for RHEV/oVirt. Thanks in advance for your feedback! Best, Sven.

[Users] full screen and different resolutions with spice
by Gianluca Cecchi 14 Feb '13

14 Feb '13

Let me know if I had better to post to spice-devel.... I'm testing oVirt 3.2 beta user portal. One client boots from a usb stick running SLAX 32bit in persistent mode with kernel 3.6.9. It is a derivative from slackware 14 where I compiled and persistently installed spice-protocol-0.12.2-noarch-1 xf86-video-qxl-0.1.0-i486-1 celt051-0.5.1.3-i486-1 pyparsing-1.5.6-i486-1 spice-0.12.0-i486-1 vala-0.17.6-i486-1 gtk-vnc-0.5.1-i486-2 virt-viewer-0.5.4-i486-1 xulrunner-15.0.1-i486-1 jdk-7u13-i586-1 spice-xpi-2.8-i486-1 so far so good. I can start firefox 17.0.1 and connect to user portal The test VM is Windows XP There was previously a session from another client pc with full screen resolution of 1366x768. Now this other client PC has a max resolution of 1024x768 I notice that it fails to start in full screen (I get the typical window where you see that the screen is bigger than the current physical) and also the Shift+F11 shortcut doesn't get any effect or error. If inside the vm I now set 1024x768 it adjusts and I can set full screen with Shift+F11 and I now can disconnect and reconnect successfully in fullscreen option. Then I close spice window and sign out from user portal (leaving the VM at its logged in screen) If now I connect again to the user portal from the 1366x768 capable client, that is Fedora 17 with firefox 18.0 and spice-gtk-python-0.12-5.fc17.x86_64 spice-xpi-2.8-2.fc17.x86_64 spice-server-0.10.1-5.fc17.x86_64 spice-gtk-tools-0.12-5.fc17.x86_64 spice-client-0.10.1-5.fc17.x86_64 spice-vdagent-0.10.1-1.fc17.x86_64 spice-gtk-0.12-5.fc17.x86_64 spice-glib-0.12-5.fc17.x86_64 spice-gtk3-0.12-5.fc17.x86_64 I connect in full screen mode and I see the Windows XP session just starts in 1024x768 (as I left it) and suddenly adjusts to the 1366x768 capable resolution Any hint on why the fiirst auto-adjust didn't work? - different spice version? - perhaps only possible to up scale but not down scale? - other? This will address situation with one user potentially connecting to the same VM in full screen mode but using different clients and so with possible different video resolutions A work around could be to power off the vm each time but it is not desirable... Also, in Fedora I get the small box at top middle of the screen where I can exit full screen for my vm. Instead in slax I have not it. WHat is the component providing that box? Thanks for all Gianluca

[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

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

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.....
