[Users] Linux sysprep
by René Koch (ovido) 22 Aug '13

Hi, Has anyone an idea what's the easiest way to sysprep Linux (CentOS 6 and RHEL 6) machines? The use case is the following: I want to create a lot of virtual machines (e.g. 100) by cloning from one template. So I create a master vm, create a template and a pool with 100 vms assigned to it and set all 100 vms to prestarted. The problem is now, that when I run "sys-unconfig" before creating the template, which does a "touch /.unconfigured" I have to go through the sysconfig-tui and set a new root password for all 100 hosts. So what I'm looking for is a script like the sysprep tool for windows which sets parameters for me automatically. I only need to change: * Hostname + set DHCP_HOSTNAME in ifcfg-eth0 (Hostname == Pool-VM-Name) for some dhcp/ddns magic :) * Clear udev network-rules * remove SSH-Keys * Remove RHN ID and join Satellite/Spacewalk-server * root-password,... should stay the same My first question is: does oVirt provide such a functionality for Linux guest out-of-the-box? I couldn't find one. I think I could solve this with virt-sysprep and virt-file, but I'm unsure if I can use it with oVirt (or only with plain libvirt): http://libguestfs.org/virt-sysprep.1.html http://libguestfs.org/virt-edit.1.html For this tools it's required that the vm is not running, as it changes files on the disk. If I'm using a before-vm-start hook, it should be save to access the disk and change content with virt-sysprep/virt-file, right? But do I have access to the disk in a before-vm-start hook? If using NFS storage I should be able to access all disks on the NFS-share, but for iSCSI/FC-LUNS - are they available on the hypervisor in this stage? Another option would be to write a custom script which is started during boot and disables itself after successful run (in the same way as firstboot - I already have such a script for RHN Satellite/Spacewalk joins). The problem here is: How do I get the (oVirt) name of this vm (would need something like virt-whoami :) )? Is the (internal oVirt) ID of this vm stored somewhere in the filesystem of this vm? I don't think so.... Thanks a lot for suggestions, René

[Users] received packet with own address as source address
by H. Haven Liu 22 Aug '13

Hello, I have a oVirt installation with 6 CentOS 6.4 hosts. Some (not all) hosts are receiving these error messages, at a frequency of once every other minute: [root@vhost1 ~]# grep "source address" /var/log/messages | tail Aug 17 11:19:20 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:21:24 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:23:29 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:25:34 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:27:39 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:29:44 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:31:49 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:33:54 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:35:59 vhost1 kernel: em1: received packet with own address as source address Aug 17 11:38:04 vhost1 kernel: em1: received packet with own address as source address These error messages are accompanied with loss of connectivity, with duration varies between a few seconds to minutes. The loss of connectivity would start just before the above error message. I don't *think* it's hardware because the "received packet with own address" error message would disappear from one of the hosts after a while. These error messages are also present whether or not any VM is running on the particular host. Here are some configurations: [root@vhost1 ~]# ifconfig em1 Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:f1 inet6 addr: aaaa::bbbb:cccc:dddd:eee1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:37413202 errors:0 dropped:0 overruns:0 frame:0 TX packets:17822315 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:32444347931 (30.2 GiB) TX bytes:13715272213 (12.7 GiB) Interrupt:16 em2 Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:f2 inet6 addr: aaaa::bbbb:cccc:dddd:eee2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:21878 errors:0 dropped:0 overruns:0 frame:0 TX packets:526 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1598070 (1.5 MiB) TX bytes:40526 (39.5 KiB) Interrupt:17 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:49 errors:0 dropped:0 overruns:0 frame:0 TX packets:49 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:9236 (9.0 KiB) TX bytes:9236 (9.0 KiB) ovirtmgmt Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:f1 inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.yyy Mask:255.255.255.0 inet6 addr: aaaa::bbbb:cccc:dddd:eeee/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:22623881 errors:0 dropped:0 overruns:0 frame:0 TX packets:9990988 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:28427312067 (26.4 GiB) TX bytes:13112553784 (12.2 GiB) private_lan Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:f2 inet addr:10.0.1.12 Bcast:10.0.1.255 Mask:255.255.255.0 inet6 addr: aaaa::bbbb:cccc:dddd:eee2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:19771 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1080512 (1.0 MiB) TX bytes:468 (468.0 b) [root@vhost1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-em1 DEVICE=em1 ONBOOT=yes HWADDR=aa:bb:cc:dd:ee:f2 BRIDGE=ovirtmgmt NM_CONTROLLED=no UUID=c25b1ad1-9646-4126-9149-be5f68bae36c DNS2=www.www.www.www DNS1=www.www.www.www HOSTNAME=vhost1.mydomain.com MTU=1500 IPV6INIT=no [root@vhost1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt DEVICE=ovirtmgmt ONBOOT=yes TYPE=Bridge DELAY=0 IPADDR=xxx.xxx.xxx.xxx NETMASK=255.255.255.0 GATEWAY=xxx.xxx.xxx.1 BOOTPROTO=none NM_CONTROLLED=no UUID=c25b1ad1-9646-4126-9149-be5f68bae36c DNS2=www.www.www.www DNS1=www.www.www.www HOSTNAME=vhost1.mydomain.com MTU=1500 IPV6INIT=no [root@vhost1 ~]# Any help is appreciated.

I didn't see anything like this in engine-config. Is it possible to do that without using host-hooks?

[Users] cant remove disks from iscsi domain
by Yuriy Demchenko 22 Aug '13

22 Aug '13

Hi, I've recently encountered a problem with removing disks from iscsi domain in my test lab - just cant remove any. Remove operation fails with message "User admin@internal failed to initiate removing of disk pg-slave1_opt from domain iscsi-store" and re-elections of SPM. After that - disk is marked as "illegal" in ovirt webinterface, however, it is _in fact_ removed from storage - lvdisplay doesn't show it and free space is updated correctly. And this happens with just about every disk/vm i try to remove. ovirt 3.2.2-el6 centos 6.4 vdsm-4.10.3-17.el6 lvm2-2.02.98-9.el6 Any tips? logs in attach -- Yuriy Demchenko

Hi, Does anyone have oVirt (or a plain KVM hypervisor) running on Infiniband where the virtual machines are bridged to an Infiniband interface (with EoIB kernel module)? I'm having issues in such a setup where vms can't communicate over this bridge... Regards, René
