Hi Petri,

Please find attached a new specific EH driver. Currently, I have not a
valid EH account, so I am not able to try it, if you could be so kind
as to try it out, I would appreciate the feedback.

In any case, this is just a temporary workaround, that just allows for
one drive and one nic to be defined in the EH VM. Just untar the
attached tarball in the root of the ONE source code, compile and
configure the EH VMM driver with a new type "eh":

   VM_MAD = [
      name       = "vmm_eh",
      executable = "one_vmm_eh",
      default    = "vmm_eh/vmm_eh.conf",
      type       = "eh" ]

A VM template like

--
EH=[NAME="bitrot",
    CPUMHZ="500",
    MEMORY="500",
    DRIVE="ide:0:0 xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
    NICMODEL="nic:0:model e1000",
    NICDHCP="nic:0:dhcp auto",
    VNCIP="vnc:ip auto",
    VNCPASSWORD="vnc:password password",
    BOOT="ide:0:0"
   ]
--

should produce a deployment file like

--
name bitrot
cpu 500
mem 500
ide:0:0 xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
boot ide:0:0
nic:0:model e1000
nic:0:dhcp auto
vnc:ip auto
vnc:password password
--

With this, I expect to rule out other issues and find out if we only
have to focus in this specific driver, which ideally should be
extended to be a proper "plain text" driver.

Best regards,

-Tino
