h2. Bitnami based on Debian 11

out of the box ERPNext is installed. This describes what else can/needs to be done:

h3. convert VirtualBox-ova to be used with KVM

untar @.ova@

<pre><code class="shell">

tar xvf bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami.ova

</code></pre>

convert @.vmdk@ to @.qcow2@ while showing 'progress'

<pre><code class="shell">

qemu-img convert -p -f vmdk -O qcow2 \

  bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami-disk1.vmdk \

  bitnami-erpnext-14.11.0-0-linux-vm-debian-11-x86_64-nami-disk1.qcow2
