qq2clone is a linux tool to simplify creating and managing copy-on-write clones of template QEMU/KVM virtual machines. It can perform batch operations in case you are working with multiple clones. There is a version of the manual page you can read online above ([man.md](https://git.j-g-web.com/jesse/qq2clone/src/branch/master/man.md)).
|
|
|
|
qq2clone has these dependences:
|
|
* virsh (qq2clone has started transitioning to use the libvirt API directly, this will not remain a dependency forever)
|
|
* Bash 4.0+
|
|
* sqlite3
|
|
* xmllint (from libxml2)
|
|
* qemu\-img
|
|
* libvirt tools:
|
|
* virt\-clone
|
|
* virt\-xml
|
|
* virt\-xml\-validate
|

# INSTALL
|
|
|
|
The file [qq2clone_installer.bash](https://git.j-g-web.com/jesse/qq2clone/raw/branch/master/qq2clone_installer.bash) is a setup script containing a self-extracting archive. If you copy and paste the following into a terminal, it will download and run.
|
|
```
|
|
curl https://git.j-g-web.com/jesse/qq2clone/raw/branch/master/qq2clone_installer.bash > .qq2clone_installer.bash 2> /dev/null &&
|
|
chmod +x .qq2clone_installer.bash &&
|
|
./.qq2clone_installer.bash

# FAQ
|
|
|
|
|
|
## How do I use this thing?
|
|
|
|
The
|
|
[manual](https://git.j-g-web.com/jesse/qq2clone/src/branch/master/man.md)
|
|
is quite detailed, and there is an
|
|
[examples](https://git.j-g-web.com/jesse/qq2clone/src/branch/master/man.
|
|
md#examples) section that may be helpful.
|
|
|
|
## Why use Bash and C when this could all be written in Python?
|
|
|
|
Just to improve my Bash skills and gain a tiny bit of familiarity with C.
|
|
Writing this in Python would certainly have been easier.
|
|
|
|
## Permission issues when making a clone
|
|
|
|
Getting an error like "Template $VMNAME refers
|
|
to /var/lib/libvirt/images/$VMNAME.qcow2, but the file
|
|
cannot be read" ? This is because libvirt is configured with a default
|
|
storage pool that you, as a non-root user are not allowed to read.
|
|
|
|
You can resolve this issue by moving the image associated with a
|
|
virtual machine to a location your user can read, changing the
|
|
ownership/permissions, and modifying the libvirt xml of the
|
|
template to point at the new image location. To modify a template machine's
|
|
XML, use qq2clone modify\-template VMNAME edit. You will have to
|
|
find the filepath of the virtual machine image in the XML and change it
|
|
to point at the location you moved it to.
