You should leave eth0 as is: dynamic IP with NAT.
You should add/configure another Network Adapter on the VM that
uses the new host only network: go to the settings of the VM:
Hi Linux gurus,

ifsysctl
IFSYSCTL(5) Network configuration IFSYSCTL(5)NAME
ifsysctl[-<interface name>] - per network interface sysctl settings
SYNOPSIS
/etc/sysconfig/network/ifsysctl
/etc/sysconfig/network/ifsysctl-<interface name>
DESCRIPTION
These files are intended to contain sysctl settings, that should be applied when a network interface is created. This are usually interface
specific settings, like:
net.ipv6.conf.eth0.use_tempaddr = 1
or
net.ipv4.conf.eth0.rp_filter = 0
The settings are applied by the /etc/sysconfig/network/scripts/ifup-sysctl script executed via /etc/udev/rules.d/77-network.rules rule (see
udev(7)), after the creation and after the rename of the interface name to its persistent name (when applicable), but before the ifup
<interface name> -o hotplug may be executed to configure the interface.
The settings are not applied by default when the NetworkManager is active (NETWORKMANAGER=yes), except when the IFSYSCTL_NETWORKMANAGER=yes
variable is set in the /etc/sysconfig/network/config file.
Settings from the ifsysctl- file are applied every time an interface has been created.
Settings from the ifsysctl-interface name file are applied when the interface with the corresponding interface name has been created.
SYNTAX
The sysctl(8) utility is required to apply the settings. It supports two separator characters for sysctl keywords: a "." in default format
and a "/" in the alternate format. Therefore the syntax is basically same to the /etc/sysctl.conf file.
Interface names may contain a ".". In the default sysctl format using a "." as separator, that is any "." in the interface name of the key-
word, has to be replaced with a "/". In the alternate sysctl format with "/" as separator, normal interface names can be used.
Optionally, the ifsysctl files may contain also the $INTERFACE and the $SYSCTL_IF variables, that are automatically replaced with the cur-
rent interface name usable in the alternate format and with the sysctl-quoted interface name for the default format, before the settings
are passed to the sysctl utility.
Note also, that settings with variables in the ifsysctl (without the -<interface name> suffix), will be applied for every interface!
Further, files with variables are not compatible to the /etc/sysctl.conf file.
EXAMPLES
Settings for "eth0" and "eth0.1" interfaces
# using "." as separator:
net.ipv6.conf.eth0.use_tempaddr = 1
net.ipv6.conf.eth0/1.use_tempaddr = 1
# using "/" as separator:
net/ipv6/conf/eth0/use_tempaddr = 1
net/ipv6/conf/eth0.0/use_tempaddr = 1
Settings with variables:
# using "." as separator:
net.ipv6.conf.$SYSCTL_IF.use_tempaddr = 1
# using "/" as separator:
net/ipv6/conf/$INTERFACE/use_tempaddr = 1
To test your ifsysctl-eth0 or ifsysctl file, use:
/etc/sysconfig/network/scripts/ifup-sysctl eth0 -o debug
