You can export distfiles via glusterfs. A single machine holds the data
while the others can fetch / upload files. Glusterfs needs to be installed
on each machine and fuse enabled in the kernel.

The init script must be changed to use openrc-run, your action will be to
update dbus as usual. Or better, open a bug report so that the init script
will be updated.

 Well, how do you do that?  Soon I want to do some Gentoo installations on
 this server.  Can I just start with HVM and switch over to PV once the
 installation is done?


From a running system lvm partitions are created for the virtual machine,
then you mount those partitions, unpack stage3 on them, chroot and follow
the same way as with installing a normal machine. You need to enable this
when compiling the kernel.




  However, you don't have
 hvm/qemu enabled so that's why your HVM guests won't start up.


 Indeed that was the problem.  Once I found that out, I finally was able to
 get it to work.  It's quite frustrating when you follow the documentation
 and yet things just don't work for unknown reasons.


Maybe try to modify the wiki for others to know?

  Can you please post some more details?

 About containers?

 There's very useful documentation about them like
 https://wiki.gentoo.org/wiki/LXC ...

 What can I say?  Virtualization with xen is like juggling with a set of
 black boxes each of which aren't exactly accessible; the
 documentation sucks, it's hard work to get it running and likewise hard
 to maintain.

 Virtualization with containers is basically as simple as running just
 another daemon.

 Which the better tool, or combination of tools is, depends on what you
 want to accomplish.  You could use containers in a VM, too, or use
 virtualbox along with containers to run the odd VMs that require full
 virtualzation.

 Again we must be afraid of speaking of daemons for fear that daemons
 might swallow us.  Finally, this fear has become reasonable.


 You mean the documentation at Gentoo about Xen sucks or the upstream
documentation? What information are you missing from there? Maybe we can
add  the missing pieces for Xen being more accessible and easier to use,
what do you think? :)

 I, currently, have the following versions for Xen running:
 app-emulation/xen-4.3.3-r3
 app-emulation/xen-tools-4.3.3-r1

 These are scheduled to be upgraded during the next maintenance window.

True, maybe we should look for problem here. Maybe you can attach your
kernel configuration or at least `grep -i xen .config`.

 hello list,

 Do i need to run mysql_upgrade after upgrading mysql 5.5  5.6 ?
 I ask because the post install text recommend this after an major upgrade.
 On the Mysql Website is a major upgrade 5.5  6.0, not 5.5  5.6
 So i ask you guys.
 Any can help me?

 thank you

Yes, you need to - it IS a major upgrade.

Check out http://dev.mysql.com/doc/refman/5.6/en/mysql-nutshell.html and
http://dev.mysql.com/doc/refman/5.6/en/upgrading-from-previous-series.html

It states:
To upgrade to 5.6 from any previous version, MySQL recommends that you
dump your tables with *mysqldump*
http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html before upgrading
and reload the dump file after upgrading. Use the --all-databases
http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html#option_mysqldump_all-databases
option to include all databases in the dump. If your databases include
stored programs, use the --routines
http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html#option_mysqldump_routines
and --events
http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html#option_mysqldump_events
options as well.

So either you dump/restore (safest but harder with downtime - except when
you run replication and switch masters) or you do upgrade on the fly and
run mysql_upgrade.

Did xen ever work on that machine?

I have no idea if it helps, but if you can play with the machine, try the
default profile and/or other xen versions.

 Hello Hydra,

 Thank you so much. I was literally about to use the default profile and

 versions. If I need to go back in time, which version is considered Stable

 me how to emerge
 an older xen version.

 Thanks for Everything!

You can try those in portage:
https://packages.gentoo.org/package/app-emulation/xen
https://packages.gentoo.org/package/app-emulation/xen-tools

Currently you have 4.3 branch (which was removed from portage a week ago or
so), try 4.2, 4.4 or 4.5, you'll see what you get.

If you want to emerge a specific version:
emerge =app-emulation/xen-4.2.5-r7 =app-emulation/xen-tools-4.2.5-r3

Don't mix xen and xen-tools branches (4.2 with 4.3) - always keep both the
same branch. The revisions don't have to match (like the above r7 for xen
and r3 for xen-tools), but the branches yes.

 I'm never sure how to debug such errors. Some googling suggested adding
 ACPI flags (ie, force, on, off), when I do that, the system just reboots
 without getting to the login prompt.

 The server is an X346 with hardward servraid 7K with raid 10.

 Your help is greatly appreciated.

Please post your emerge --info information along with xen and xen-tools

 It took me a bit of fiddling but I think I figured it out.

 I had to get the directory structure correct ... now I have

 /etc/ansible/inventories/group_vars/

 with files like siteA, siteB, siteC ... containing the specific variables.

 At first I always had /etc/ansible/group_vars ... and that didn't work
 at all!

 Now I am able to have such a small playbook for the whole dhcp-config of
 one site:

 ---
 - hosts: siteA
   user: root
   roles:
 - dhcpd

 and this pulls the group_vars from

 /etc/ansible/inventories/group_vars/siteA

 and applies it to the dhcpd-role
 and overrides /etc/ansible/roles/dhcpd/defaults/main.yml ... which was
 my original goal!

 nice!

 Stefan



By the way, you don't need to have it in /etc/ansible, feel free to have it
anywhere.

It would be wise to upgrade per partes, not doing a large leap from

  would the group_vars override the vars defined in defaults/main.yml ?
