= CentOS 6 and Microsoft Linux Integration Tools 3.2 for Hyper-V =

A quick and dirty howto for using Linux Integration Tools 3.2 for Hyper-V R2 on CentOS / RHEL 6 (tested on 6.2)

Original french version of this howto available here:
* [[http://www.badministrateur.com/fr/node/119|http://www.badministrateur.com/fr/node/119]]

== Prerequesites ==

Host OS: Microsoft Windows Server 2008 / 2008 R2 / Hyper-V Server / Hyper-V Server R2

Guest OS: RHEL 6.0, 6.1, CentOS 6.0 (as stated by Microsoft)


== Basic installation ==

Grab a copy of the LinuxIC tools here http://www.microsoft.com/en-us/download/details.aspx?id=28188
After having inserted the iso in the virtual dvd drive, install the tools by:

# mount /dev/cdrom /mnt
# mkdir /opt/linuxIC
# cp -R /dev/cdrom /opt/linuxIC
# umount /dev/cdrom
# /opt/linuxIC/install.sh

Now reboot and test whether the installation was successful:

# lsmod | grep hv
should output something like

hv_netvsc              21591  0
hv_utils                5661  0
hv_mouse                4217  0
hv_timesource           1079  0 [permanent]
hv_storvsc              9087  3
hv_vmbus               29482  5 hv_netvsc,hv_utils,hv_mouse,hv_timesource,hv_storvsc,[permanent]

== The ethernet problem ==

Now the point is that no ethernet card is detected, nor created while installing CentOS, so no ifcfg script exists.
To get your ethernet running, ensure you have a synthetic ethernet card on the VM, and note its MAC address.

You'll have to create a couple of files:

/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=static

IPADDR=192.168.17.252

NETMASK=255.255.255.0

NETWORK=192.168.17.0

BROADCAST=255.255.255.255

GATEWAY=192.168.17.254

# Remember to put your MAC address here, unless it won't work

HWADDR=00:15:5D:xx:xx:xx

ONBOOT=yes

TYPE=ethernet


/etc/sysconfig/network

NETWORKING=yes

HOSTNAME=badministrateur.test.local

/etc/resolv.conf

search test.local

nameserver 192.168.17.254

Once these files are created, you can finally enable your ethernet card by typing

# ifup eth0

Well... this was easier in earlier installments of the LinuxIC tools, even the legacy ethernet card didn't do the trick for me.
