Engine currently uses IDE bus for all cdrom devices. That is fine for i440fx chipset, but not for q35. As we would like to move to q35 tech preview or even default at some point, different bus must be used (e.g. scsi, sata).
Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone.
Moving to 4.1, as it looks like it'll be 7.3 based.
*** Bug 1322248 has been marked as a duplicate of this bug. ***
this is minor and more of a bug, blocking a possible tech preview during 4.0 lifecycle (there's no code on our side needed other than this fix AFAIK, so as soon as 7.3 is out we can semi-support q35...)
i'll trade it with another 4.0 bug and move back
Moving from 4.0 alpha to 4.0 beta since 4.0 alpha has been already released and bug is not ON_QA.
verified on :
oVirt Engine Version: 4.1.0-0.0.master.20160606111312.gitc7af584.el7.centos
1. create VM with CD-rom
2. change the emulated machine to q35 , and later for pc-i440fx-rhel7.2.0
3. start the VM
4. look at the VM devices
For VM with q35 chipset - > SATA added
For VM with i440fx chipset -> controller added.
oVirt 4.0.0 has been released, closing current release.
Hi, I tried related scenario.
When I boot a VM with i440fx+ide(cdrom), VM can start successfully.
After that, I edit the VM to 'q35' machine type, then VM can not start with the following error:
VM jiyan-1 is down with error. Exit message: unsupported configuration: IDE controllers are unsupported for this QEMU binary or machine type.
However, I can not find where to disable IDE controller in web UI. Could you please help to check this issue, thx very much.
