Comment 1 cshao 2016-05-23 07:35:37 UTC 
I can reproduce this issue.

Test version:
RHEVH-7.2-20160520.t.0-RHEVH-x86_64-dvd1.iso
imgbased-0.6-0.1.el7ev.noarch
ovirt-hosted-engine-setup-1.3.6.1-1.el7ev.noarch
ovirt-hosted-engine-ha-1.3.5.5-1.el7ev.noarch
rhevm-appliance-20160515.0-1.el7ev.3.6.ova

Test steps:
1. Install RHEVH-ng-7.2-20160520 with default storage layout.
2. Disabled NetworkManager and start hosted-engine setup from cockpit.
3. #rpm -ivh 20160515.0-1.el7ev.3.6.rpm on NGN
4. Setup Hosted Engine step by step
5. Please specify the device to boot the VM from (choose disk for the oVirt engine appliance) (cdrom, disk, pxe) [disk]: [disk]
6. The following appliance have been found on your system:
[1] - The RHEV-M Appliance image (OVA) - 20160515.0-1.el7ev
[2] - Directly select an OVA file
Please select an appliance (1, 2) [1]: 1
7. Press enter key with default directory [/var/tmp]

Test result:
It report "Not enough space in the temporary directory".

Please specify path to a temporary directory with at least 50 GB [/var/tmp]:
Not enough space in the temporary directory

NOTE：
If we specify path to another path, the HE deploy can continue.

Comment 3 Red Hat Bugzilla Rules Engine 2016-06-16 07:06:31 UTC 
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.

#c2 was occurred due to failed to analysis hostname, after add hostname to /etc/hosts, the issue was gone. so please ignore comments 2.


Change back bug status to ON_QA.
Comment 6 cshao 2016-06-16 08:17:59 UTC 
Custom set var partition should resolved this issue, but will met Bug 1344900 - Hosted Engine deployment failed. So I will verify this bug after bug 1344900 fixed.

What did yuo have to do with the host name?

I want to understand why this step was necessary

I thought that edit the /etc/hosts file is for analysis hostname, if without analysis, it will failed during register host to engine, so I did it every time.
But actually analysis is unnecessary.

After re-check #c2, seem it is the different error, I will report a new one to trace the new issue
Comment 9 cshao 2016-07-20 09:09:29 UTC 
Test version:
redhat-virtualization-host-4.0-20160714.3
imgbased-0.7.2-0.1.el7ev.noarch
redhat-release-virtualization-host-4.0-0.20.el7.x86_64
ovirt-hosted-engine-ha-2.0.1-1.el7ev.noarch
ovirt-hosted-engine-setup-2.0.1-1.el7ev.noarch
rhevm-appliance-20160714.0-1.el7ev.4.0.ova 

Test step:

 During deploy HE(with the default size of /var) via cockpit, it will pop-up "Not enough space in the temporary directory [/var/tmp]". We can specify a larger partition manually(e.g. /home), and deploy HE can successful with the new path.   

So the bug is fixed, change bug status to VERIFIED.
