[one-users] KVM default NAT networking and port forwarding

2013-11-02 Thread Andy Coates

Hey,

I have a very basic setup that requires no ON configured networking, just
the default NAT that KVM provides out of the box.

I'm not sure how to properly define an interface to achieve this.  I've
got it working via the RAW section by adding:

interface type='network'source network='default'/ model
type='virtio'//interface

This works and it provides the default NAT interface, but is that how it
should be done?  I ask because the second issue I have is that I cannot
port forward from the host.  According to the KVM docs, using these
parameters (added via qemu:commandline option) should forward TCP port 3389:

-net user,hostfwd=tcp::3389-:3389

It doesn't work though, and I have a feeling this is because of how I
defined the network/interface above.  The host does start to listen on port
3389 when KVM starts, I can see that through netstat/lsof - it just doesn't
seem to connect through to the VM.

Any ideas?

Thanks.

[one-users] OpenNebual Virtual Router 4.2 login failed, password needed.

2013-11-02 Thread yuchang_subscribe

Hi,

The problem is still bothering me.
Now I run this router with opennebula,and the following configuration:
router-template.one:
NAME   = router
CPU= 0.1
MEMORY = 256
DISK   = [ IMAGE = router ]
NIC= [ NETWORK = cloud ]
FEATURES=[ acpi=no ]
GRAPHICS = [
TYPE= vnc,
LISTEN  = 0.0.0.0
]
CONTEXT= [
hostname = router,
ip_public = 172.16.100.210,
files = /var/lib/one/init.sh /var/lib/one/.ssh/id_dsa.pub,
target= hdb,
root_pubkey = id_dsa.pub
]
init.sh:
#!/usr/bin/env bash
if [ -n $HOSTNAME ];then
   echo $HOSTNAME /etc/HOSTNAME
   hostname $HOSTNAME
fi
if [ -n $IP_PUBLIC ];then
   ifconfig eth0 $IP_PUBLIC
fi
echo context initing...
if [ -f /mnt/context/$ROOT_PUBKEY ];then
cat /mnt/context/$ROOT_PUBKEY /root/.ssh/authorized_keys
fi

But ttylinux-template works.In ttylinux-template.one,the context's target was 
modified to hdc.I saw the log context initing... from ttylinux's console.

Where was my configuration wrong?

Best Regards
yuchang

Sorry,I didn't setup ROOT_PUBKEY,because I tried to run this router without 
opennebula environment.
So I should try this Router under opennebula next  time.

thank you .

Hello Yuchang,


Have you set up ROOT_PUBKEY or ROOT_PASSWORD in the CONTEXT of the Virtual 
Router VMs' template, as stated in the Virtual Router documentation [1] in 
Configuration section?

Good Will,

Hi Mark,

Yes, we have some issues with the paths used by every distro. We are
working to get the packages right, so it is no need to update the paths...

Thanks again for the feedback

 Hi Mark

 It seems that your domain is trying to boot from /vmlinuz that cannot be
 found in the host. This primitive is not in your original template as shown
 in the template of VM 13 (there is no OSKERNEL).

 So this is most probably coming from the driver configuration file. Could
 you check (and remove) /etc/vmm_exec/vmm_exec_kvm.conf  for a line setting
 KERNEL to /vmlinuz?

 Cheers

 Ruben

 Hi Mike

 Thank you very much for sharing, great doc!

 Could we get more details about still does not work for me (VMs don't
 instantiate)? So we can clear any issue and complete the document?


 Thanks

 Ruben

 Perhaps this will help others, trying to do what I am attempting to do --
 just bring up ONE 4.2 for a Developer/DevOps Cloud + Host node.   In my
 case, I must  write some Cloud automation code in Python, against the OCCI
 APIs.

 Any changes or comments appreciated!   Thank you.
