Doc Text:	Previously, the Manager virtual machine did not have adequate ownership of the host's CD-ROM in a self-hosted engine deployment. This meant that deployment failed when installing the Manager from CD-ROM as the virtual machine would lose access rights to the CD-ROM immediately after installation of the operating system. Now, the qemu user has been added to the cdrom group so that the Manager virtual machine retains access rights to the CD-ROM and deployment continues as expected.	Story Points:	---

Description Roman Hodain 2014-03-28 13:57:11 UTC

Description of problem:
	The newly crated VM for self hosted engine fails to start if the
installation source is cdrom (/dev/cdrom). The reason is the rights. vdsm:kvm
does not have rights to read that device. If the rights are set correctly the Vm
starts, but as soon as the OS installation is finished the CD is ejected and the
rights are reset to the default which forces the next steps od the installation
fail for the same reason.

Version-Release number of selected component (if applicable):
	ovirt-hosted-engine-setup-1.0.0-6.el6ev.noarch

How reproducible:
	100%

Steps to Reproduce:
	1. # hosted-engine --deploy
	2. Choose the cdrom installation source and point it to /dev/cdrom

Actual results:
	Deployment fails

	RHEV-M is successfully deployed

	/dev/cdrom => /dev/sr0 in most cases

Comment 1 Sandro Bonazzola 2014-03-28 14:21:48 UTC

This is the first time I see someone trying to use the hardware device instead of the iso image.

Workaround may be add vdsm user to cdrom group.

Comment 2 Sandro Bonazzola 2014-04-08 12:36:59 UTC

Roman: also qemu user need to be added to cdrom group.
Fixing this on vdsm side so also vdsClient will allow to boot from local CD-ROM.

Comment 3 Dan Kenigsberg 2014-04-08 13:04:41 UTC

Could you attach the vdsm.log traceback of the failing operation?

Comment 4 Sandro Bonazzola 2014-04-11 06:53:19 UTC

No need for the logs, reproduced here. Patch pushed for both vdsm and hosted-engine setup.

Comment 5 Sandro Bonazzola 2014-04-15 06:31:33 UTC

All patches merged on upstream master and 3.4 branches.
