Re: [ovirt-users] Is it mandatory to have fixed IP addres for eth0, for installtion of OVirt
Hi John, You can use DHCP on eth0 before installing ovirt.

Re: [ovirt-users] using Network_Custom_Properties for firewalld zone?
Hi Jorick, I am not sure that Network_Custom_Properties is what you are looking for. With network custom properties you can only configure bridge or ethtool opts. So bridge opts doesn't suit you as it is only for specific configuration of the bridge on the specific NIC and with ethtool you don't configure firewall as well, unless there is a command that I am not familiar with.

Hi, Trying to add the ZONE field to the NIC's in oVirt as I'm trying to use Firewalld instead of iptables. Manually it works fine but when I try to set a custom property, it doesn't apply. http://www.ovirt.org/Features/Network_Custom_Properties I can't figure out if this should work or I should use a different method.

[ovirt-users] My feedback on network setting after installing OVirt
Hi All, Like to give my feedback about how the network interface behaved after OVirt I have used CentOS 6.6 64 bit, updated Ovirt stable from the repo Now after the installation, and configuration you get "ovirtmgmt" interface and "ovirtmgmt" interface gets the IP address and everything is fine . Now reboot it result is that when you give ifconfig , eth0 is not displayed and "ovirtmgmt" do not have IP address This stage solved by giving ifconfig eth0 up and restarting the network, it will give "ovirtmgmt" an IP now I tested it using different installation, with DHCP or manual configuration for eth0 , in both the case the same experience Giving my feedback, thanks ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] Maximum VM memory
Dear ovirt users, We have a special machine which has 1 TB RAM. The idea is to have 3-4 VMs on there which should be split like 85/5/5/5 % of total RAM. I have three questions: 1. Is there any reason not to put up a VM with so much RAM 2. How can I increase the maximum RAM size for 64 bit VMs? 3. How can I create a new OS for the VM creation that supports > 16 GB ? (Right now i have to choose RHEL 64 bits even for Debian systems) Thank you for your help, — Christophe ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I have three questions: 1. Is there any reason not to put up a VM with so much RAM One reason I can think of - migration of a VM with 1TB ram will most likely never complete and time out. I have problems migrating machines with 64GB or more of RAM on RHEV, If you don't need live migration then you should be OK.

Re: [ovirt-users] missing disk after storage domain expansion
Ok, so, After _*a lot*_ of unsuccessful approach, I finally connected to postegre DB directly. Browsing the tables I found “unregistered_ovf_of_entities” where there is a reference of the missing disk @ovf:diskId:4ab070c0-fb16-452d-8521-4ff0b004aef3 @ovf:size:210 @ovf:actual_size:210 @ovf:vm_snapshot_id:2e24b255-bb84-4284-8785-e2a042045882 @ovf:fileRef:16736ce0-a9df-410f-9f29-3a28364cdd41/4ab070c0-fb16-452d-8521-4ff0b004aef3 @ovf:format:http://www.vmware.com/specifications/vmdk.html#sparse @ovf:volume-format:RAW @ovf:volume-type:Preallocated @ovf:disk-interface:VirtIO @ovf:boot:false @ovf:disk-alias:hertz_disk5 @ovf:disk-description:disk for SYBASE installation, on SAN shared storage @ovf:wipe-after-delete:false However, I’ve been unable to find any other helpful details. I guess the disk is not recoverable at this point? Any guru who has a good ovirt DB kwnoledge willing to give me some advice? Thanks as usual AG *From:* Andrea Ghelardi [mailto:a.ghela...@iontrading.com] *Sent:* Thursday, May 07, 2015 6:08 PM *To:* 'users@ovirt.org' *Subject:* missing disk after storage domain expansion Hi gentlemen, I recently found an error on 1 of my storages: it was complaining about no free space but the VM was running and disk operational. Since I needed to perform some maintenance on the VM, I shut it down and at restart VM couldn’t boot up properly. Checked VM via console and a disk was missing. Edited fstab (luckily this disk was not root but heck! It had a Sybase DB on it!) and restarted VM this time ok. Since the disk resides on the dstore with no space, I expanded the iSCSI LUN, then refreshed multipath on hosts, then resized PVs and now ovirt is showing the correct size (logs do not complain anymore on no free space). BUUUT Now disk is missing. It is not shown anymore on Disks tab nor anywhere else. Problem is that storage shows 214GB occupancy (size of the missing disk) so data is there but cannot find it anymore. Logs show original disk creation, errors from the lack of space, refresh of the storage size and then no more references on the disk. What can I do to find those missing ~210GBs?
