Hello,
My company is rolling out a new setup, which was originally going to use
openvz 6. With the release of vz7, we'd like to take a moment to see if it
meets our requirements.
I have a handful of questions that I have no been able to find answers to,
as the documentation is rather spare.
1) Am I able to create containers using libvirt? (specifically from XML
passed to virsh) What does this XML look like?
Max, please comment.
Yes you are. Below is an example:
<domain type='vz'>
<name>your-ct-name</name>
<uuid>5869cd3e-13fc-4e69-b99a-d37c020987b6</uuid>
<memory unit='KiB'>524288</memory>
<currentMemory unit='KiB'>524288</currentMemory>
<vcpu placement='static'>1</vcpu>
<os>
<type arch='x86_64'>exe</type>
<init>/sbin/init</init>
</os>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<filesystem type='file' accessmode='passthrough'>
<driver type='ploop' format='ploop'/>
<source file='/path/to/your/ploop/disk/directory'/>
<target dir='/'/>
</filesystem>
<interface type='bridge'>
<mac address='fa:16:3e:c6:5c:90'/>
<source bridge='some-bridge'/>
<target dev='veth1234'/>
<link state='up'/>
</interface>
<input type='mouse' bus='parallels'/>
<input type='keyboard' bus='parallels'/>
<graphics type='vnc' port='-1' autoport='yes' listen='10.27.68.3'>
<listen type='address' address='10.27.68.3'/>
</graphics>
<video>
<model type='parallels' heads='1'/>
</video>
</devices>
</domain>
2) Are OS Templates any different than openvz 6.0?
Yes, OpenVZ 7 uses EZ templates.
See https://docs.openvz.org/openvz_users_guide.webhelp/_managing_templates.html
3) Has vz7 been tested with openvswitch and veth?
it was tested via intermediate linux bridge
4) Does networking in vz7 work like KVM does now that we're using KVM for
the hypervisor?
you can use veth interfaces in CTs, which can be plugged into an arbitrary
bridge on the host
5) I noticed vz7 supports qcow2, In my testing containers created with
prlctl were still using ploop. Is there a trick to enable this?
ploop format is for containers, qcow2 - for virtual machines. There is no trick
to make containers use qcow2 at the moment.
Dima, please comment.
6) Can VZ7 hosts be kickstarted? I thought I read somewhere that kickstart
was a "premium" feature only available in the paid version.
Installation using Kickstart is available in OpenVZ 7 too -
https://docs.openvz.org/openvz_installation_using_pxe_guide.webhelp/_creating_a_kickstart_file.html
I'm sure I'll have a bunch more questions, but this is where I'm starting
at. Thank you.
