== SMEServer v8.0 in OpenVZ ==
This is a work in progress and does not yet work.

== Initial CentOS Virtual Machine ==
* Start with a [http://download.openvz.org/contrib/template/precreated/centos-5-i386-minimal.tar.gz CentOS 5 Minimal Template] in Proxmox VE OpenVZ Container
* Rename template to conform to ProxmoxVE naming convention and move to template cache
<pre>
cd /var/lib/vz/template/cache
wget http://download.openvz.org/contrib/template/precreated/centos-5-i386-minimal.tar.gz
mv centos-5-i386-minimal.tar.gz centos-5-minimal_5_i386.tar.gz
</pre>
* 512 MB RAM / 8 GB HDD / IP address assigned during VM creation / SELinux disabled / sshd enabled
* Start Container
* 88 RPMs pre-installed [[Media:CentOS_5_Minimal_Installed_RPM_List.txt|'''list''']]
 rpm -qa --qf "%{n}-%{v}-%{r}.%{arch}.rpm\n" > /tmp/centOS5_minimal_after_yum_with_arch.txt
* 590 RPMs in SME8 installed [[Media:SME_8_Installed_RPM_List.txt|'''list''']] - on Atom Hardware with 2GB RAM / 320 GB HDD
* Check the current CentOS Version with <tt>'''cat /etc/redhat-release'''</tt> to be '''CentOS release 5 (Final)'''

</pre>

* Check the installed groups with <tt>yum grouplist</tt>:
<pre>
Installed Groups:
   System Tools
   Yum Utilities
Available Groups:
   Administration
....
</pre>

The RPMs that now stand installed are listed [[Media:CentOS5_Yum_Enabled_RPMs.txt|'''here.''']].

== Install screen ==
To enable background updates, screen is installed.
 yum install screen nano mlocate
It is invoked / re-attached with <tt>'''screen -aR scrname'''</tt> and detached from the session with <tt>'''Ctrl-A d'''</tt>.

Set '''keepcache=1''' in '''/etc/yum.conf''' to retain the rpms for further use.

Take a backup of the Virtual Machine now before the mess that begins next.

== Install the SME 8 RPMs ==
* Remove all current repos in /etc/yum.repos.d
 mkdir /tmp/repo.bak
 mv /etc/yum.repos.d/*.repo /tmp/repo.bak/
* Upload '''/etc/yum.repos.d/[[Media:SME8_sme-base.repo.txt|sme_base.repo]]'''
 wget http://wiki.contribs.org/images/3/30/SME8_sme-base.repo.txt -O /etc/yum.repos.d/sme-base.repo
* YUM install sme rpms
 yum --disablerepo=base,updates,extras upgrade --nogpg
 yum install smeserver\* e-smith\* *.sme.* --enablerepo=smeos8,smeupdates8 --nogpgcheck
* 287 MB / 374 RPMs Installed
* SMEServer uses runlevels 7 and 4
 rm -f /etc/rc4.d/*
 cp -a /etc/rc7.d/* /etc/rc4.d/
* Now get the [[Media:SME8_VZ_PostYUM.txt|'''list''']] of installed RPMs
<pre>
ABC=`rpm -qa`
echo ${ABC} > sme8_rpms_after_yum.txt
ABC=
</pre>
* Some RPMs get removed and others get updated. 
* Use a MySQL database to check the differences:
<syntaxhighlight lang="sql">
CREATE DATABASE `rpmmatch`CHARACTER SET latin1 COLLATE latin1_general_ci; 
CREATE TABLE `rpmmatch`.`smerpms`( `rpmname` VARCHAR(100) NOT NULL, PRIMARY KEY (`rpmname`) ); 
CREATE TABLE `rpmmatch`.`c5minrpms`( `rpmname` VARCHAR(100) NOT NULL, PRIMARY KEY (`rpmname`) ); 
LOAD DATA LOW_PRIORITY LOCAL INFILE 'C:\\smerpms.csv' INTO TABLE `rpmmatch`.`smerpms` FIELDS ESCAPED BY '\\' TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r\n' (`rpmname`); 
LOAD DATA LOW_PRIORITY LOCAL INFILE 'C:\\c5minrpms.csv' INTO TABLE `rpmmatch`.`c5minrpms` FIELDS ESCAPED BY '\\' TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r\n' (`rpmname`); 
UPDATE c5minrpms SET rpmname=REPLACE(rpmname, ".(none).rpm", "") WHERE 1;
UPDATE smerpms   SET rpmname=REPLACE(rpmname, ".(none).rpm", "") WHERE 1;
SELECT a.* FROM c5minrpms a LEFT JOIN smerpms b USING (rpmname) WHERE b.rpmname IS NULL ORDER BY rpmname; 
SELECT a.* FROM smerpms a LEFT JOIN c5minrpms b USING (rpmname) WHERE b.rpmname IS NULL ORDER BY rpmname; 
</syntaxhighlight>
* 75 packages difference including 2 kernels not needed

== Install Missing Packages ==
Since networking and sshd will not be working, ssh into the ProxmoxVE host and use '''vzctl enter <VEID>''' to work further. Edit the file /etc/sysconfig/network-scripts/ifcfg-venet0:
<pre>
DEVICE=venet0
BOOTPROTO=static
ONBOOT=yes
IPADDR=127.0.0.1
NETMASK=255.255.255.255
BROADCAST=0.0.0.0
IPV6INIT="yes"
</pre>
to be something like:
<pre>
DEVICE=venet0
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.60.110
NETMASK=255.255.255.0
GATEWAY=192.168.60.1
NETWORK=192.168.60.0
BROADCAST=192.168.60.255
IPV6INIT="yes"
</pre>
Restart Networking with:
 ifdown venet0 && ifup venet0

Alternatively, the VLANs can be used:
<pre>
# cat /etc/sysconfig/network-scripts/ifcfg-venet0
DEVICE=venet0
BOOTPROTO=static
ONBOOT=yes
IPADDR=127.0.0.1
NETMASK=255.255.255.255
BROADCAST=0.0.0.0
IPV6INIT="yes"

# cat /etc/sysconfig/network-scripts/ifcfg-venet0:0
DEVICE=venet0:0
ONBOOT=yes
IPADDR=192.168.22.107
NETMASK=255.255.255.255

ifdown venet0 && ifup venet0
ifdown venet0:0 && ifup venet0:0
</pre>

Now install the missing packages:
 yum install mlocate xz xz-libs \
     zip unzip which vixie-cron vim-enhanced vim-common usbutils traceroute tnef time telnet tcpdump \
     syslinux sysfsutils strace setserial safecat rsync rp-pppoe rpm-build qmail-qfilter \
     pyxf86config perl-suidperl kudzu libgomp lockdev lsof maildrop man minicom mkbootdisk mod_ssl \
     mt-st mutt newt anacron at authconfig bc bind-libs bind-utils cdrecord cyrus-sasl \
     cyrus-sasl-md5 dhclient dhcp diald diald-top distcache dosfstools eject fetchmail ftp \
     gettext glib groff hdparm hesiod iptraf iptstate isdn4k-utils --nogpgcheck
* '''maildrop''' complained of key requirement and hence the '''--nogpgcheck'''
* '''pcmciautils''' is dependent on the '''kernel''' and hence avoided
* Restart the Virtual machine and set the IP again as done earlier (we need to address the VM startup sauce to do this atutmagically):
 signal-event post-upgrade; signal-event reboot

== Package Differences ==
One RPM from the pre-installed RPMs in the template remains:
 beecrypt-4.1.2-10.1.1.i386.rpm
Two kernels and one kernel dependent RPM were not installed:
 kernel-2.6.18-308.4.1.el5.i686.rpm
 kernel-2.6.18-348.1.1.el5.i686.rpm
 pcmciautils-014-5.i386.rpm
The final list of 574 RPMs and 4 extra keys are [[Media:SME8_RPMs_In_OpenVZ.txt|'''here''']].

=== /var/lib/modules ===
This folder is empty as no CentOS kernel was installed.

=== dhcpd ===
dhcpd was exiting and respawning itself unable to get an IP. IT hardcoded in OpenVZ on NIC side for server only mode. Shut it down with:
 service dhcpd stop
 chkconfig dhcpd off

== Errors ==
=== Init Boot Log ===
On startup, the VM emits the following error:
<pre>
Applying Intel CPU microcode update: FATAL: 
Could not load /lib/modules/2.6.32-7-pve/modules.dep: No such file or directory
/etc/rc.d/init.d/microcode_ctl: microcode device /dev/cpu/microcode doesn't exist?
Starting system logger: [ OK ] 
</pre>

The said package is:
</pre>
rpm -qa | grep -i microcode
microcode_ctl-1.17-3.el5
</pre>

* Removing it would mean the removal of 41 '''smeserver''' and '''e-smith''' rpms which are dependent.
* Ref: [http://forums.fedoraforum.org/showthread.php?t=236507 Forum Post].
* Ref: [http://www.centos.org/docs/5/html/5.2/Virtualization/sect-Virtualization-Troubleshooting-Microcode_error_during_guest_boot.html CentOS Docs]
* Hence:
 /sbin/service microcode_ctl stop
 /sbin/chkconfig --del microcode_ctl
* Copy the /lib/modules/2.6.32-7-pve folder from the host to the guest.
* Initial Boot Log of the VM will show the following error:
<pre>
iscsid is stopped
Starting iSCSI daemon: WARNING: Error inserting libiscsi (/lib/modules/2.6.32-7-pve/kernel/drivers/scsi/libiscsi.ko): Unknown symbol in module, or unknown parameter (see dmesg)

</pre>
* Remove offending RPM and it's dependancies:
<pre>
# yum remove iscsi-initiator-utils

Removed:
  iscsi-initiator-utils.i386 0:6.2.0.872-16.el5

Dependency Removed:
  mkbootdisk.i386 0:1.5.3-2.1                            mkinitrd.i386 0:5.1.19.6-79.el5
</pre>

== Remove needless services ==
Ref: http://wiki.openvz.org/Physical_to_container
 rpm --nodeps -e acpid auditd kudzu netplugd microcode_ctl lvm2_monitor irqbalance ntpd lm_sensors
If it complains with some being not installed like '''auditd netplugd lvm2_monitor ntpd''', then 
 rpm --nodeps -e acpid kudzu microcode_ctl irqbalance lm_sensors

== Current Status ==
* Networking and sshd works
* Pinging outside works
* yum update works
* '''venet0''' and '''venet0:0''' not recognised inside SMEServer
** Try to take a look at /etc/udev/rules.d/70-persisten-net.rules. Specifically the MAC address [RequestedDeletion ]
* login as '''root''' and type '''console''' and enter the configuration menu
* Can test internet access
* elinks does not browse server-manager
* configuration of server '''fails''' since no network card is recognised as it relies on '''udev'''
* devnodes '''/dev/tun''' is available in the container
