[Users] trying ovirt-live in test day

[Itamar Heim]

i wanted to do something "easy", so i decided to test ovirt-live.
but there wasn't any for 3.3, so i'll just build it and test

this is where i got today:

1. finding: no ovirt-live in repos for test day

ok, i'll build it myself.

2. finding: the ovirt-live page[1] has no data on how to build it (link 
to ovirt-live git repo, readme in git repo, etc.)

su -c "yum install git"[2]
git clone git://github.com/oVirt/ovirt-live
cd ovirt-live/centos
./build.sh

3. finding: build.sh is modifying a git managed file[3] - this shouldn't 
happen.

4. finding: i didn't notice build.sh warned me that:

4.1 "You need to be root to perform this command."
since it continued downloading tinycore rather than exit with error

4.2 yum install -y livecd-tools
probably should be in readme to pre-install it, and ./build.sh should 
check and exit with error, but not do the installation itself

5. yum install -y livecd-tools
finding: no livecd-toold in rhel - referencing an rpm or instructions to 
build from source are needed

cd ~
git clone git://git.fedorahosted.org/livecd
cd livecd
su -c "make install"
cd ~/ovirt-live/centos

6. finding: re-running ./build.sh download tinycore and yad each time 
instead of checking is-modified-since

7. finding: missing check on selinux is disabled (required by 
livecd-creator according to [4])

(again looked in log, no info on screen):
Traceback (most recent call last):
   File "/usr/bin/livecd-creator", line 26, in <module>
     import selinux
ImportError: No module named selinux

disabled selinux.
su -c "setenforce 0"
(didn't resolve the selinux import error...)

8. finding: no validation libselinux-python is installed
su -c "yum install -y libselinux-python"

9. finding: missing pykickstart
from log: ImportError: No module named pykickstart.parser
su -c "yum localinstall -y 
http://mirror.centos.org/centos/6/os/i386/Packages/pykickstart-1.74.12-1.el6.noarch.rpm"

(mirror link is from [6])

10. finding: missing rhpl
from log: ImportError: No module named rhpl.keyboard

su -c "yum localinstall -y 
http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rhpl-0.221-2.el6.rf.x86_64.rpm"

(mirror link is from[5])

11. finding: (again) need to run as root
"You must run /usr/bin/livecd-creator as root"

12. finding: noise output when re-running ./build.sh
mkdir: cannot create directory `oVirtLiveFiles/rpms/': File exists
mkdir: cannot create directory `oVirtLiveFiles/iso/': File exists
mv: cannot stat `*.rpm': No such file or directory
mv: cannot stat `*.iso': No such file or directory

13. finding: awk warnings when running ./build.sh
awk: warning: escape sequence `\-' treated as plain `-'
awk: warning: escape sequence `\/' treated as plain `/'

14. finding: ovirt not spelled oVirt
Using title 'Ovirt Live' and product 'Ovirt Live'

15. finding: YumRepo Error: All mirror URLs are not using ftp, http[s] 
or file.
  Eg. 6Server is not a valid release or hasnt been released yet/
removing mirrorlist with no valid mirrors: 
/var/tmp/imgcreate-W8OJmj/install_root/var/cache/yum/base/mirrorlist.txt
...
yum.Errors.RepoError: Cannot retrieve repository metadata (repomd.xml) 
for repository: base. Please verify its path and try again

16. repo issues
(not all are bugs)

16.1. (not a bug) - I'm runnning on rhel, not centos, so base repo is 
different for me than centos

16.2 (not a bug) - had to comment out yum-plugin-fastestmirror, not in 
rhel (should be optional...)

16.3  finding: should be configurable - ovirt repo version - git is 
static to 3.2, i needed beta. should be a parameter

16.4 finding: missing jboss-as package?
added to kickstart link to stable repo

16.5 finding: livecd-tools-13.4.4-2.el6.x86_64 requires /sbin/extlinux
doesn't help installing it, needs to be in the kickstart list of repos

i did some more fiddling with repos here, trying to run this on RHEL 
rather than centos.

17. finding: Error creating Live CD : Unable to run 
['/usr/bin/firewall-offline-cmd', '--enabled', '--service=mdns']!

hmmm - there is no firewall on .el6?
