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

1. 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)

2. 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]

3. 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.
