On host
---------
$ ping 10.0.0.2
PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_req=1 ttl=61 time=3.09 ms

64 bytes from 10.0.0.2: icmp_req=5 ttl=61 time=3.08 ms

it works.

$ ssh -X satimis at 10.0.0.2

No password can satisfy it.


At this junction I expect to clarify whether it needs 2 NICs, one for 10.0.0.2 and one for 192.168.x.x?  

It YES I have to create vboxnet0 and vboxnet1, the virtual NIC.  There is only ONE physical NIC on this PC.  

Also I have to edit /etc/sysconfig/network-scripts/
ifcfg-lo
ifcfg-p2p1

$ cat /etc/sysconfig/network-scripts/ifcfg-lo 
DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback

$ cat /etc/sysconfig/network-scripts/ifcfg-p2p1 
UUID="a145edf3-1d26-43cd-be09-140de3df2d6f"
NM_CONTROLLED="yes"
HWADDR="08:00:27:AD:A1:1F"
BOOTPROTO="dhcp"
DEVICE="p2p1"
ONBOOT="yes"

It will becomes a little bid complicate.

$ nova list
ERROR: You must provide a username via either --os_username or env[OS_USERNAME]

none of follows can work
$ nova list --os_username ADMIN

--os_username=ADMIN
env[ADMIN]
etc.

$ nova delete d08a6804-3532-4611-81b3-5d8cc8f2a321

Same here.  Please help.  Thanks

Whether to run;

$ sudo chown nova:nova -R /var/lib/nova/CA/*

Then;
sudo nova-manage nova-cert
?

Thanks
