Re: [ovirt-users] yum update command is failed

2014-12-09 Thread Ilan Hirsfeld
Hi,

I forgot to indicate I would like to install oVrit Vdsm but I can't do it
because the problems have been reported in previous mail.

Regards,
Ilan.

 Hi,

 My name's Ilan and I'm a new user.
 I installed CentOS 7 64 bit with VMware Player as guest and try 'yum
 update' to get newest application and get error as mentioned below. It
 seem me the installation determines the IP address as loopback and I don't
 know how enable it as real/virtual.
 I copy  paste the findings from Linux and Windows.
 Any help will be blessed.

 Regards,
 Ilan.

 error

  One of the configured repositories failed (Unknown),
  and yum doesn't have enough cached data to continue. At this point the
 only
  safe thing yum can do is fail. There are a few ways to work fix this:



  1. Contact the upstream for the repository and get them to fix the
 problem.

  2. Reconfigure the baseurl/etc. for the repository, to point to a
 working
 upstream. This is most often useful if you are using a newer
 distribution release than is supported by the repository (and the
 packages for the previous distribution release still work).

  3. Disable the repository, so yum won't use it by default. Yum will
 then
 just ignore the repository until you permanently enable it again
 or use
 --enablerepo for temporary usage:

 yum-config-manager --disable repoid

  4. Configure the failing repository to be skipped, if it is
 unavailable.
 Note that yum will try to contact the repo. when it runs most
 commands,
 so will have to try and fail each time (and thus. yum will be be
 much
 slower). If it is a very temporary problem though, this is often a
 nice
 compromise:

 yum-config-manager --save
 --setopt=repoid.skip_if_unavailable=true
 Cannot find a valid baseurl for repo: base/7/x86_64

This is a network connectivity error, or a yum problem.

Please make sure your network works (you can access the internet).
This error has nothing to do with ovirt.

Furthermore, why do you want to install vdsm inside a vm?
For most purposes it won't work anyway or you get bad performance
because nested virtualization (virtualization in virtualization)
is very slow.

It is just sufficient for demo purposes (in this case you
would want ovirt all in one installation).

Yeah, Could not resolve host: mirrorlist.centos.org suggests that
there's no DNS (and no networking at all) inside your VM.

I'm no expert in vmplayer, but have you defined a VM with networking
there?

What is the output of `ifconfig -a` within your VM?

Does a simple `ping 8.8.8.8` work?

Dan.
