CentOS virt - Feb 2010 - Moving vmware guests to a CentOS KVM server

Hi all,

  I need to move ten CentOS/RHEL 5.4 vmware guests from a vmware ESXi 4 host to
a
CentOS 5.4 KVM host (fully patched). But I have two doubts.

  First: all these guests have two e1000 network drivers defined as a eth0,eth1
and
modprobe.conf file is the same on all:

  alias eth0 e1000
  alias eth1 e1000
  alias net-pf-10 off
  options ipv6 disable=1

  Can I change e1000 driver to virtio_net driver without problems and then
update
kernel???


  Second doubt: all MAC address are defined with vmware range
(00:50:56:XX:XX:XX)
and I have configured all with HWADDR option under ifcfg-ethX files. Do I need
to
change all MAC address to KVM range or can I keep vmware range??

  I don't need to convert virtual disks because all these guests are
installed on an
iSCSI luns under Solaris/ZFS servers ...

  Many thanks.

I would keep the mac addresses, otherwise the guests will
see them as new network cards and require you to make
changes. 

I would also just use the e1000 emulation. Theres nothing
better about the virtio devices...
