Let's check the basics, just in case:<br>
a) The ttylinux machine you are using is the one downloaded from our
site, so it is correctly contextualized.<br>
b) And you are trying to access the VM 192.168.0.6 from a machine in
the same 192.168.0.X network, right?<br>
<br>
You may want to try adding another NIC attribute to the template,
attached to your public network. This way you could access the VM from
anywhere, not just the private network.<br>
</blockquote>
We area trying to add another NIC to our template. This is the public
vnet file we have prepared:<br>
<br>
NAME = "public"<br>
TYPE = FIXED<br>
<br>
#Now we'll use the cluster private network (physical)<br>
BRIDGE = br0<br>
LEASES = [IP=62.101.90.195]<br>
<br>
this public IP is one of our subnet 62.101.90.192/27 without DHCP.<br>
<br>
If we create a VM starting from ttylinux template you provided with
this public vnet, I can start the machine but in the boot log I can see
this problem:<br>
<br>
/etc/rc.d/rc.startup/10.network: line 78 : ./ifup-eth0.template: No
such file or directory<br>
<br>
Anyway I can log in through virt-manager and ifconfig show this<br>
<br>
# ifconfig<br>
eth0 Link encap:Ethernet HWaddr 00:03:3E:65:5A:C3 <br>
inet addr:62.101.90.195 Bcast:62.101.90.223
Mask:255.255.255.224<br>
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1<br>
RX packets:74 errors:0 dropped:0 overruns:0 frame:0<br>
TX packets:35 errors:0 dropped:0 overruns:0 carrier:0<br>
collisions:0 txqueuelen:1000 <br>
RX bytes:8683 (8.4 KiB) TX bytes:4177 (4.0 KiB)<br>

<br>
lo Link encap:Local Loopback <br>
inet addr:127.0.0.1 Mask:255.0.0.0<br>
UP LOOPBACK RUNNING MTU:16436 Metric:1<br>

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0<br>
collisions:0 txqueuelen:0 <br>
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)<br>
<br>
<br>
and there is the problem:<br>
<br>
# cat /etc/sysconfig/network-scripts/ifcfg-eth0<br>
ENABLE=yes<br>
NAME=Ethernet<br>
IPADDRESS=62.101.90.195<br>
CIDRLEN=24<br>
NETWORK=62.101.90.0<br>
NETMASK=255.255.255.0<br>
BROADCAST=62.101.90.255<br>
DHCP=no<br>
GATEWAY=62.101.90.1<br>
<br>
some network parameters are not correct (like NETWORK; NETMASK and
BROADCAST). In fact, if I change them manually and restart the network,
everything works.<br>
Is there any way to configure it in the "publi.net" vnet file?<br>
<br>
Thank you,<br>
Andrea<br>

Did you manage to access the VM through ssh? or are you using VNC?<br>

</div>
Not yet, I can access through virt-manager or virsh to the VM but not
through ssh, cause network doesn't work.
<div><br>
<blockquote type="cite"><br>
If you can't ping anything from the VM, maybe you could try adding
other VMs to that private network and check if they see each other.<br>
Or just configure the VM template to attach a network interface to the
public network.<br>

Any ideas?

<br>
unfortunately also running the fsck on the .img didn't solve the
problem. Here my situation:<br>
<br>
- 1 x frontend: ubuntu 10.04 - KVM - NFS<br>
- 1 x cluster node: ubuntu 10.04 - KVM - NFS<br>
<br>
A ttylinux VM has been started correctly on the worker node. From the
front end:<br>

The ttylinux VM shows this:<br>
# ifconfig <br>

but I cannot ping anything from this VM<br>

To help the investigation, here the bctrl show command on the cluester

run the command "qemu-syetm_x86 ttylinux.img" from the ttylinux image
directory..you can see a window and will start boot ttylinux...<br>
and asked password for recover from the disk failure after entering the
password "password" you just run the command "fsck /dev/hda1" it will
remove the error and properly shutdown the system by typing the command
halt or shutdown ....after the correct shutdown and close the window
...and try to run the ttylinux again and verify...is it ok then again
shutdown correctly and copy this ttylinux image for your cloud .....<br>

with a similar problem, but also fsck on that VM doesn't help me to

<br>
Could it be related to the network configuration of my kvm host?</tt> <br>
