XO Installation on an offline system

lpfernandes

Hi,

I'm trying to install XO on a server that is running xcp-ng. I downloaded the image from https://xen-orchestra.com/products/unified (xoa_unified.xva) and used the script http://xoa.io/deploy with a minor change to use a local image rather than to the download.
I have specified a static IP however the built image always uses eth0 as the default network uuid, but in my machine only eht1 is in use.

 xe pif-list

uuid ( RO) : 6c7ef06d-0317-05a5-ec28-9465219642d1
device ( RO): **eth0**
currently-attached ( RO): true
VLAN ( RO): -1
network-uuid ( RO): **09e0fa61-f5b2-531e-712a-e25a5a4a05f9**

uuid ( RO): 56afb8cc-0bfb-cd2b-23f3-5a596d478070
device ( RO): eth1
currently-attached ( RO): true
VLAN ( RO): -1
network-uuid ( RO): 6a084467-1c83-5aea-1950-f95e85c8b754

 xe vif-list

uuid ( RO): 3868eec8-92b0-5652-82f1-7ba1c6a55e4d
vm-uuid ( RO): 2380a8fd-925b-719c-67ed-c0d4217857af
device ( RO): 0
network-uuid ( RO): **09e0fa61-f5b2-531e-712a-e25a5a4a05f9**

I have tried to add a second device using:

xe vif-create network-uuid=6a084467-1c83-5aea-1950-f95e85c8b754 vm-uuid=2380a8fd-925b-719c-67ed-c0d4217857af

However when I try to configure the new vif using this command:

xe vif-configure-ipv4 uuid=2616c0af-0f60-b6bc-b7cf-71276997edf2 mode=static address=**.***.***.***/25 gateway=**.***.***.***

I get the error:

You attempted an operation on a VM which lacks the feature.
vm: 2380a8fd-925b-719c-67ed-c0d4217857af (XOA)

Any ideas or suggestions, thanks?

You can't do it while the VM is live.

@olivierlambert Same error if the vm is shutdown

That's not the way to make the IP configuration of a VM.

You just remove the vif, then recreate one on the right network. Then, from inside the VM, you create the IP configuration you like.

lpfernandes

@olivierlambert Right ok but how to I connect to the VM if I dont have the correct IP configuration?

olivierlambert

Accessing the VM console via another tool.

Alternatively, pass the values via xenstore in the VM object, because XOA got a special script reading values from there.

Take a look at the deploy script to know where to put those values.

lpfernandes

@olivierlambert I have tried already to pass the details using:

xe vm-param-set uuid=$uuid xenstore-data:vm-data/ip=$ip xenstore-data:vm-data/netmask=$netmask xenstore-data:vm-data/gateway=$gateway xenstore-data:vm-data/dns=$dns

Still did not work, and regarding the use of another tool to access the console, what would you suggest to use I have tried xenconsole but its just hangs?

Thanks

olivierlambert

Are you sure you correctly passed the right values? (ie your variable in your example were correctly assigned?)

Because the script should have fetched them on boot, also if it's the first and only vif it will be eth0 for the VM, so that should work Double check you have only one VIF.

lpfernandes

Ok I managed to change by first destroying the vif and creating a new one, than the VM took the values already set by the script.

xe vif-destroy uuid=$vifid
xe vif-create network-uuid=$nuuid vm-uuid=$uuid device=0 mac=random

However when I start the web page after logging in I just get a logo for the loading

olivierlambert

It's using websocket, so your fw might close the connection. Please try in HTTPS.

@lpfernandes

Same occurrence using either http or https, both just display the loading logo. Is there any configuration change required ?

olivierlambert

Any plugin that could block in your browser? Same result in Firefox?

lpfernandes

@olivierlambert No plugins installed, same result on both IE and Firefox

lpfernandes

@lpfernandes All I see is a JS error "SyntaxError: invalid property id"

olivierlambert

@julien-f or @pdonias will take a look when then can.

lpfernandes

@olivierlambert Thanks
