Description haiyang,dong 2012-12-03 08:44:13 UTC

Description of problem:
Make livecd to USB disk via livecd-iso-to-disk ,then plug that USB media into local host. Boot from PXE.
Enter into ROOT/HOSTVG_STORAGE_PAGE to check that rhev-h still filtered out live usb device in these pages.

when boot from CD media,  rhev-h will list live usb device in ROOT/HOSTVG_STORAGE_PAGE,
so no this issue on booting from cd media

Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20121126.0.el6

How reproducible:
100% 
  
Steps to Reproduce:
1.Make livecd to USB disk via livecd-iso-to-disk
2.Plug that USB media into local host and boot from PXE
3.clean install rhev-h via TUI
4.Enter ROOT/HOSTVG_STORAGE_PAGE

Actual result:
After Step 4,check that rhev-h still filtered out live usb device in these pages.

Expect result:
rhev-h should also list live usb device in ROOT/HOSTVG_STORAGE_PAGE when boot from PXE

Additional info:
Maybe the root cause is that:
When boot from PXE
Python 2.6.6 (r266:84292, Oct 12 2012, 14:23:48) 
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ovirtnode.ovirtfunctions import *
>>> get_live_disk()
'/dev/sdb1'
>>> exit()

so rhev-h will filter out live usb device(/dev/sdb) in ROOT/HOSTVG_STORAGE_PAGE

When boot from CD media
Python 2.6.6 (r266:84292, Oct 12 2012, 14:26:36) 
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ovirtnode.ovirtfunctions import *
>>> get_live_disk()
'sr0'
>>> exit()

so rhev-h will list live usb device(/dev/sdb) in ROOT/HOSTVG_STORAGE_PAGE

if/elif/else loggic needed some tweaks can you try this testbuild:


http://jenkins.virt.bos.redhat.com/jenkins/job/rhev-hypervisor-6/lastSuccessfulBuild/artifact/rhev-hypervisor6-6.4-20121126.0.auto1171.el6.iso


booted from pxe
cd/usb inserted, cd device will show up in list

Plug live usb media/CD into local host and booted rhev-hypervisor6-6.4-20121126.0.auto1171.el6 from PXE, can see that:
rhev-h will list live usb device(/dev/sdb) in ROOT/HOSTVG_STORAGE_PAGE

so this iso work well for this bug

Comment 10 Mike Burns 2013-06-10 22:17:36 UTC

Need to rework the filter logic

Test by booting from:

pxe
cdrom
usb (livecd-iso-to-disk)
usb (dd)

Comment 15 Mike Burns 2013-06-27 18:05:20 UTC

This will require reworking the logic for detecting the live device.

We need to ensure that the logic handles the following operating systems

EL6 and derivatives
Fedora 18/19

And the following cases:

1. Boot from disk (/dev/mapper/, /dev/vda, etc)
2. Boot from usb (livecd-iso-to-disk)
3. Boot from usb (dd)
4. Boot from pxe
5. Boot from iso
6. Boot from cd
7. Boot from virtual media

#2 and #3 are *not* the same
#5 and #6 might be the same
#7 is definitely different than #6 (some virtual media don't recognize the label on the disk.

Comment 18 Fabian Deutsch 2014-07-24 16:02:14 UTC

This is a mass change, moving bugs of merged patches into MODIFIED.

Please correct the state, if you think that the move was not justified.

Comment 19 haiyang,dong 2014-11-11 12:12:16 UTC

Test version:
rhev-hypervisor6-6.6-20141107.0.iso
ovirt-node-3.1.0-0.25.20141107gitf6dc7b9.el6.noarch


Test Steps
1.Make livecd to USB disk via livecd-iso-to-disk
2.Plug that USB media into local host and boot from PXE
3.clean install rhev-h via TUI
4.Enter ROOT/HOSTVG_STORAGE_PAGE

Test results:
rhev-h will list live usb device in ROOT/HOSTVG_STORAGE_PAGE when boot from PXE

so this bug has been fixed in in rhevh 6.6 for RHEV 3.5 bulid version, change the status into "VERIFIED"
