My Server is DELL R710 Raid0 (146GB*4)
1. Write the image to a 16GB flash drive and boot from USB
2. Log in and stop all services: "/etc/init.d/wanosd stop-all"
3. dd if=/dev/sda of=/dev/sdb
4. reboot &  boot from Hdisk
 l found login wanos via "tc' , don't need password and
 "ifconfig " no lan0 & wan0 only lo
there is not folder "wanos" in /etc/

Hi, yes it appears to be raid or scsi compatibility. If the raid drive is available when booting from flash then the drive can be used for the datastore without the dd process. Alternatively please install ESXi as a base system

ESXi will also allow other vm's to run on the hardware since the hardware is most likely significantly more powerful than required for 20mbps.

Hi, the VM network interfaces needs to be connected to physical interfaces. It is done via the Host > Configuration > Networking tab.

There are some manual steps here: http://wanos.co/wan-optimization/vsphere-vswitch-guide/
But the virtual interfaces are already added in the OVA package. The virtual interfaces just needs to be connected to the correct physical ports and promiscuous enabled. ( This is assuming two dedicated physical interfaces will be used and not VLANS).

Screenshots looks OK. Now I suspect the port on the switch where the R710 connects needs to be in trunk mode.

Screenshot of the vswitch config:


Regarding dd for windows, rather not use it, seems lots of people have problems with it. Win Disk Imager is ok.

R710 two ports connect to CISCO switches, switches and virtual switches mode are trunk, and my other VM network is normal

How can i write img file to hdisk via “Win32 Disk Imager”  (I know USB is ok)

after i done this command ,network is ok
ifconfig wan0 down & ifconfig wan0 up
ifconfig lan0 down  ifconfig lan0 up
ifconfig tun0 down  ifconfig tun0 up

And I have found wanos must ping gateway first after reboot or configuration applied,then network can work normal

Ok great!

That is an ESXi quirk that happens when there are bridge/promiscuous portsgroups connected on the same vSwitch with multiple physical NICs. If the vSwitch only has one physical interface this does not happen. While virtual networking is useful, we recommend using dedicated physical interfaces for the Wanos VM where possible. If not, possibly look at creating a separate vSwitch for the ASA and Wanos wan0

To use Win Disk Imager to write to a SATA drive, an external HDD bay can be used.
