You have to use the disks.clone parameter, for example:
#!/bin/sh -ex

curl \
--verbose \
--insecure \
--request POST \

Re: [ovirt-users] VM autoconfiguration
I spent a day with testing and went into two situations: - cloud-init set up everything except root password - cloud-init set up everything except network What does it mean? Let me explain: When I remove HWADDR from ifcfg-eth0 in template, everything works (network, ssh with key), but can't login through console or ssh with password. So I think it is not set. When I forgot to remove HWADDR line, root password is set but network not work ofcourse. I added custom command with runcmd to remove this line and restart network - everything works. Stupid hack ... So root password cloud-init setting depends on network settings. Is this cloud-init bug? Jiri Dne 23.9.2014 v 8:30 Shahar Havivi napsal(a): On 22.09.14 19:37, J.

[ovirt-users] User permissions for user portal
Hello, I can't figure out right user permissions. I can add user which can do just this through user portal: - see and change status of VM (including Power Off) - remote console - change CD (+ maybe os type) Change status and console (without power off) comes with UserRole, power off and change CD comes with UserVmManager. But UserVmManager brigns also wide options to manage network interfaces, disks etc, what is unsafe for me to delegate it to this user.

So cannot believe oVirt does not support this ... Thanks, J.M. Dne 20.9.2014 v 12:11 Oved Ourfali napsal(a): You can create your own custom user roles via the administration portal.

Re: [ovirt-users] VM Network Interfaces - bad cluster network and VLAN assignment
Ahoj :) After huge testing today :) I see it is problem just if I add NICs after VM creation and automatically assigned MACs are 00:1a:4a:c4:e4:11 and 00:1a:4a:c4:e4:ef. In this case there is also desc alphabetical sorting of nic (sorting by MAC?). This problem is NOT when: - NICs are added in time of VM creation (windows New Virtual Machine, tab General) - 1 NIC is added in time of VM creation and 1 added later - when all NICs are added later and oVirt assign another MAC J. Dne 17.9.2014 11:16, David Jaša napsal(a): Ahoj Jiří, Are you sure that the networks are indeed wrong, for example that guest's NIC with ...:11 MAC is plugged to br0 network and ...:ef NIC is plugged to br1 network? If so that would be a serious bug. I thing however that you just see guest OS NIC naming race conditions, maybe if ovirt's NIC names would be prefixed with nic- instead of eth- by default, such confusions wouldn't happen... For some reference, bug [1] is implemented consistent NIC order in the portal and [2] to be able to modify pci addresses as well (as they are used by some OSs to base NIC naming on).
