Hello,
OK here it goes:

*From my iMAC*
I am able to ping both the Control Server (1.1.75.194) and the KVM Host
(1.1.74.146) but not the VM (1.1.74.147).
*This is my "Red LAN NJ01" configuration:*
NAME = "Red LAN NJ01 "
TYPE = FIXED
# We have to bind this network to 'virbr0' for Internet Access
BRIDGE = virbr0
LEASES = [ IP="1.1.74.147"]
LEASES = [ IP="1.1.74.148"]
LEASES = [ IP="1.1.74.149"]
LEASES = [ IP="1.1.74.150"]
GATEWAY = 1.1.74.145
DNS = 208.67.222.222
*This is my ttylinux.one configuration:*
NAME = ttylinux
CPU = 0.1
MEMORY = 64
DISK = [ IMAGE_ID = 2 ]
NIC = [ NETWORK_ID = 13 ]
FEATURES=[ acpi="no" ]
CONTEXT = [
hostname = "$NAME",
ip_public = "1.1.74.147",
files = "/srv/cloud/one/one-templates/init.sh
/srv/cloud/one/.ssh/id_rsa.pub",
target = "hdc",
root_pubkey = "id_rsa.pub",
username = "oneadmin",
user_pubkey = "id_rsa.pub"
]
Interestly, I did an ifconfig in the VM and I see the the Broadcast and
the Netmask are incorrect.
# ifconfig
eth0 Link encap:Ethernet HWaddr 02:00:41:62:4A:93
inet addr:1.1.74.147 Bcast:1.255.255.255 Mask:255.0.0.0

So it looks like a virtual network configuration issue somewhere but I
can't put my hand on it.
Best regards,

Hello,
I am trying to get the test ttylinux VM going after a few days of
putting together bits of documentation to get a better
understanding of KVM. So far the VM is running and I am able to
ssh into it from the Control Server and the Host but I am unable
to ping it from any other external IP.
I checked the relevant FAQ:
"http://wiki.opennebula.org/faq#my_vm_is_running_but_i_get_no_answer_from_pings_what_s_wrong";
<http://wiki.opennebula.org/faq#my_vm_is_running_but_i_get_no_answer_from_pings_what_s_wrong>
and made some comments below.
There are several reasons for this, check:
*
You have created a network with a valid bridge in the nodes
of your cluster
Yes, the bridge configuration is as follows:
** ( Real IP has been substituted ) **
auto eth0
iface eth0 inet manual
auto virbr0
iface virbr0 inet static
address 1.1.74.146
netmask 255.255.255.248
network 1.1.74.144
gateway 1.1.74.145
broadcast 1.1.74.151
bridge_ports eth0
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off
*
You have defined a NIC attribute in your VM attached to that
network
NAME = ttylinux
CPU = 0.1
MEMORY = 64
DISK = [ IMAGE_ID = 2 ]
NIC = [ NETWORK_ID = 10 ]
FEATURES=[ acpi="no" ]
CONTEXT = [
hostname = "$NAME",
ip_public = "1.1.74.147",
files = "/srv/cloud/one/one-templates/init.sh
/srv/cloud/one/.ssh/id_rsa.pub",
target = "hdc",
root_pubkey = "id_rsa.pub",
username = "oneadmin",
user_pubkey = "id_rsa.pub"
]
*
The VM is prepared to configure the interface to use a valid
IP in that network. You can:
o
Configure the VM to dynamically configure the IP using
its MAC address (Contextualzation
<http://wiki.opennebula.org/documentation:rel2.2:cong>)
o
Configure the VM to statically set a given IP of the network
o
Put a DHCP server attached to that network
Yes, the VM is statically set a given IP of the network.
*
Also be sure that you are pinging the VM from a host with a
route to the network
Yes, I am able to ping and ssh the VM from the Control Server
which is on the same public VLAN but I am unable to ping that IP
from my network for example.
oneadmin@cps:~/one-templates$ onevnet list
ID USER GROUP NAME TYPE BRIDGE PUB LEASES
10 oneadmin oneadmin Red LAN NJ01 F virbr0 No 1
5 oneadmin oneadmin Blue LAN R virbr1 No 0
oneadmin@cps:~/one-templates$ onevm list
ID USER GROUP NAME STAT CPU MEM
HOSTNAME TIME
13 oneadmin oneadmin ttylinux runn 4 64M
vmh-usnjewr-eqi 00 01:09:54
Opennebula Version = 3.0.0 compiled from source
Installation Type = Self contained in /srv/cloud/one
Hypervisor = KVM
Control Server OS: Ubuntu 11.04 LTS
KVM Host OS: Ubuntu 11.10 LTS
Storage = Non Shared File System
Any assistance will be much appreciated.
Thanks in Advance.
Errol
