You can use xen-tools to create a small server

In a Debian based distro:

sudo apt install -y lvm2 debootstrap libconfig-inifiles-perl
libdata-validate-domain-perl libdata-validate-ip-perl
libdata-validate-uri-perl libfile-slurp-perl libfile-which-perl
libsort-versions-perl libterm-ui-perl libtext-template-perl openssh-client
perl debian-archive-keyring rinse libtest-notabs-perl

git clone https://github.com/xen-tools/xen-tools.git
cd xen-tools
make install

xen-create-image --hostname=test \
--ip=10.0.0.60 \
--broadcast=10.0.0.255 \
--gateway=10.0.0.1 \
--netmask=255.255.255.0 \
--memory=128mb \
--dir=/var/tpcv/xen_images \
--dist=trusty


Obviously you should replace the values for your network environment

Thank you.
I did that command and logs are:

https://paste.ubuntu.com/p/nVk5tXb2zk/

Is everything OK? How can I launch my VM?

I think that you need to read the documentation about setup the bridge, and
the xl tool... Those are prerequisite for the commands that I send to you

Thank you.
I used "xl create /etc/xen/test.cfg" and got below error:

$ sudo xl create /etc/xen/test.cfg
Parsing config from /etc/xen/test.cfg
libxl: error: libxl_exec.c:117:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge online [176788] exited with error status 1

libxl: error: libxl_domain.c:920:domain_destroy_cb: Domain 3:Destruction of domain failed


I changed config as below:

vif=['10.0.0.60,script=vif-route']

And added below lines to "/etc/xen/xend-config.sxp" file:
(network-script network-route)
(vif-script vif-route)

Then commented out below line in "xl.conf" file:
vif.default.script="vif-route"

But, I got below error:

$ sudo xl create /etc/xen/test.cfg

libxl: error: libxl_exec.c:117:libxl_report_child_exitstatus: /etc/xen/scripts/vif-route online [286618] exited with error status 1

How can I solve it?

Did you setup a bridge?


Assuming a debian like dist:

# Xen bridge - you can also use the 192.168.0.0
auto xenbr0
iface xenbr0 inet static
bridge_ports none
bridge_stp no
address 10.0.0.1 # or 192.168.1.1
netmask 255.255.255.0 # or 255.255.255.0
network 10.0.0.0 # 192.168.1.0
broadcast 10.0.0.255 # 192.168.1.255
# if needed setup nameserver approprietaly
# dns-nameserver 193.136.212.1


then:

#sudo sysctl -w net.ipv4.ip_forward=1 also edit /etc/sysctl.conf
sudo sysctl -w net.ipv4.ip_forward=1

sudo iptables -A FORWARD --in-interface xenbr0 -j ACCEPT
sudo iptables --table nat -A POSTROUTING --out-interface XXXX -j MASQUERADE

sudo apt-get install iptables-persistent
sudo /etc/init.d/iptables-persistent save
sudo /etc/init.d/iptables-persistent reload

# Inside the Gest:
ifconfig eth0 10.0.0.2 up
route add default gw 10.0.0.1

Hey Jason,

It's on /etc/network/interfaces

But, next time asking in this list, try first looking into the main

Thank you Charles.

I did:

$ sudo iptables --table nat -A POSTROUTING --out-interface enp0s3 -j MASQUERADE
$ sudo xl create /etc/xen/test.cfg
Parsing config from /etc/xen/test.cfg
$ sudo xl list

Domain-0                                     0   875     2     r-----     735.4
test                                         2   128     1     -b----       3.5

And I can ping the IP address:

$ ping 10.0.0.60
PING 10.0.0.60 (10.0.0.60) 56(84) bytes of data.
64 bytes from 10.0.0.60: icmp_seq=1 ttl=64 time=0.555 ms
64 bytes from 10.0.0.60: icmp_seq=2 ttl=64 time=0.470 ms

After launched the VM:

But VM can't boot:

Why?

It did boot; you can see messages from the guest kernel there. But it
looks like the VM you booted could not find its root filesystem.
Show us your guest config file for this domU.

I'm using Lubuntu:

And:

$ cat /etc/fstab 
# /etc/fstab: static file system information.

Anything wrong?

From the previous log you posted, the kernel had booted so I think
that pygrub was able to correctly find the guest's kernel and
initramfs.

The guest's kernel also did find its root filesystem (note how it
configured a bunch of things that it would have needed access to
/etc for) but then bailed out at the end saying "errors were found
while checking the disk drive for /." I think that message comes
from the init system.

So I *think* your guest config file is okay (I'd give it a bit more
RAM though), it's finding its root filesystem okay, but maybe your
/etc/fstab above is wrong.

If if I were you I'd check that the filesystem with UUID
4d7a5a50-9288-424d-a383-2f6888b908a1 is actually there, i.e. that
that is its UUID.

For an easier life and to prove the theory I might ensure that
/dev/xvda2 is used for the root in your /etc/fstab. If that worked
then I would try to find out why the UUID was wrong.

I'm not familiar with Lubuntu but it looks like possibly you could
also press "I" to ignore and it might just carry on booting.

Cheers,
Andy

Also, may I ask why you chose to start with a Linux distribution
from 2014, that is already EOL for standard support (security
support only now), Upstart init system and 3.x kernel?

This is ancient and IMHO not a good test bed for trying out anything
new.

Cheers,
Andy

Thank you.
More information about UUID is:

$ sudo blkid 
/dev/sda1: UUID="4d7a5a50-9288-424d-a383-2f6888b908a1" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="bcad374b-01"
/dev/sdb1: UUID="dvzaw6-MJeq-sm7f-f3uo-GQbq-UEn4-2R51dx" TYPE="LVM2_member" PARTUUID="0ed18b03-01"

I changed the VM setting to:

vcpus       = '2'
memory      = '2048'

But not matter and when I entered "I", "S" or "M" key then nothing happened.

I'm using Lubuntu because it is lightweight.

Sorry, I don't know what "Serious errors were found while checking
the disk drive for /" means here exactly. I think when you solve
that issue you will be alright.

A few lines earlier it did mention it had mounted root from xvda2,
so that bit is okay:

Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.
Begin: Running /scripts/local-premount ... done.

I don't understand why you picked the 14.x version of Lubuntu from
2014 though, when the 18.x LTS version exists.

Hello,

Yes it provides ...

Have you tried to mount the images manually and check if it was configured
properly?
