XOA can't start after installation and contradictory messages

MajorTom

Hi.
While installing XOA the official way:

[host:~]# bash -c "$(curl -s http://xoa.io/deploy)"

Welcome to the XOA auto-deploy script!

Network settings:
IP address? [dhcp] 10.1.0.4
Netmask? [255.255.255.0]
Gateway? 10.1.0.254
dns? [8.8.8.8] NS.ip.address.here
Importing XOA VMâŚ
Booting XOA VMâŚ
There are no suitable hosts to start this VM on.
The following table provides per-host reasons for why the VM could not be started:

host    : Cannot start here [Host cannot attach to network: 77097537-8e7b-f375-abd6-d638ac42abcc (Pool-wide network associated with eth0)]


There were no hosts available to complete the specified operation.
Waiting for your XOA to be readyâŚ

Your XOA is ready on https://10.1.0.4/

Default UI credentials: admin@admin.net/admin
Default console credentials: xoa/xoa

VM UUID: e58ce2ec-4fe4-5a9f-70b1-f6a5ca204946

So, cannot start or is ready on https://10.1.0.4/ ?

No, it's not ready. It's shut and the Networking tab in XCP-ng-Center shows:

"Network 0 192.168.100.144".

Maybe the reason is that the address 10.1.0.4 which I'm trying to give to XOA is from one of the VLANs, but the installer tries to use a "Network 0" (which doesn't exist at all, as the NIC is Bond0+1). But why does it configure 192.168.100.144? It doesn't exist here. BTW, at a previous XOA installation the issue was the same, but the (bad) address was 192.168.100.190. Some tip here maybe.

Then I manually start the VM, login at the console and set the correct IP address, but for less experienced users these contradictory messages can be misleading.

This is an edge case when you can't boot XOA because XAPI tries to find a match to "network 0" of the template (the xva file). Usually, 99% of users have a network 0. That's why you are the first to report this problem. In short, a non-handled error case.
The "old" IP you can see is the one before changing, the one XOA had before being transformed into a template.

The thing is: this is how XVA files are working, and there's no pre-deploy option to select a network for a XVA.

MajorTom

@olivierlambert I see, thanks.

Anyway, maybe the installation script could check whether the XOA really started and not misleadingly inform Your XOA is ready on https://10.1.0.4/?

olivierlambert

As I said, it's an edge case we didn't think before. So, obviously, we'll improve this (but first we need to reproduce the issue). Can you print the output of xe network-list on this host? I'm trying to understand why you don't have a network 0.

MajorTom

@olivierlambert

Sure.

Thanks, we'll try to see if we could detect this case for an update on deploy script

MajorTom

@olivierlambert You're welcome.

As a start, to prevent false positive message that the XOA VM is ready at some IP address, the script could check the power-state in the result of

# xe vm-list name-label=XOA
uuid ( RO)           : e58ce2ec-4fe4-5a9f-70b1-f6a5ca204946
     name-label ( RW): XOA
    power-state ( RO): running

(whether running or not).

I realize this is an old topic, but that make me realize it's unfortunate that this hasn't been fixed at this point.
I tried to use the command line to install XOA and it complains with the same error. In my case it's because I am using bonded interfaces just like the OP. Surprising that it doesn't come up more often but I guess if you set this up before you bond the interfaces it's not an issue.

olivierlambert

@Low351 that's because the deploy script isn't the main/advised way to deploy XOA So it's lower in our backlog (vs the deploy UI from our website or even from within XCP-ng web page)

edit: I'll check with our teams if someone could add network selection quickly in the deploy script (which will hopefully solve the issue)

edit 2: investigating IF this will solve the issue first

julien-f

The deploy script is a very basic tool used as a fallback when the UI deploy is not available.

@Low351 Are you able to use the web quick deploy? https://xen-orchestra.com/#!/xoa

low351 0

@julien-f Yes, I realize that after. I finally just downloaded the ova and installed it that way, it's working fine. Thank you!

Low351

@olivierlambert It would be nice to have but as you stated originally not a real priority. I installed using the .ova without issue. Thanks for responding.

olivierlambert

FYI, we modified the deploy script to be able to automatically modify XOA's VIF to run on the management network.

So even in case of using only bonded networks like @Low351, this will now work.
