error when default storage pool is missing

[screeley44]

1. my work laptop is rhel 6.5
2. I have created f21 VM (named miqbuild.rhs)
3. from the f21 VM I have successfully performed these commands:
   dnf copr enable fsimonce/virt-deploy
   dnf install virt-deploy virt-address
4. Now when I try to create the instance, I get this:

[root@miqbuild ~]# virt-deploy create test01 fedora-21
Traceback (most recent call last):
File "/usr/bin/virt-deploy", line 9, in
load_entry_point('virt-deploy==0.1.6', 'console_scripts', 'virt-deploy')()

pool = conn.storagePoolLookupByName(kwargs['pool'])
File "/usr/lib64/python2.7/site-packages/libvirt.py", line 4305, in storagePoolLookupByName
if ret is None:raise libvirtError('virStoragePoolLookupByName() failed', conn=self)
libvirt.libvirtError: Storage pool not found: no storage pool with matching name 'default'

Any idea what I'm missing at this point, or maybe my approach is completely wrong?

@screeley44 what version are you using? (virt-deploy --version)

Latest version on copr is 0.1.6.

Can you check that you have the default pool defined in libvirt:

# virsh pool-list
 Name                 State      Autostart 
-------------------------------------------
 default              active     yes     

Thanks

You can try to define the pool with:

# virsh pool-define /dev/stdin <<EOF
<pool type='dir'>
  <name>default</name>
  <target>
    <path>/var/lib/libvirt/images</path>
  </target>
</pool>
EOF

virsh pool-start default
virsh pool-autostart default

[screeley44]

that worked!! Thanks!!

Name State Autostart

default active yes

Marking this as enhancement/help-wanted because adding the default storage pool when missing will improve user experience.

Hi,
I've met similar issue. I have minimal installation and I've installed virt-deploy and it seems that "default" pool is not defined.
It is caused also by missing dependency, what is not directly needed but this dependency create this pool.
it is package "virt-manager"
after installation of that package and reboot machine, pool is aviable.

So I'm not sure what is better solution, install dependendend virt-manager or create default pool + default network in own setup as workaround.
From this point of view I cannot decide what is better.
it is connected with another issue:
#10

So my point of view is, that it would be nice, to not use default pool and default network but be able to config own pool for disc and net.

My mentioned solution should also solve another issue:
I'm running virt-deploy under normal user ( not root) and I've added policy to
/etc/polkit-1/localauthority/50-local.d/50-org.example-libvirt-remote-access.pkla
to allow some group work with virsh qemu:///system
All virsh qemu:///system comands works then well, but qemu-img command does not have access to /var/lib/libvirt/images (default pool location), so in case virt-deploy under normal user create this pool in some other dir where user/group has access it will be better. (/var/lib/libvirt/images/_fedora-21-x86_64.qcow2: qemu-img exited with error status 1.)

Hi,
otherwise I found, that this default pool is created after command virt-manager is called (probably virt-manager do some init of "default" pool)
installation of virt-manager is not enouht

error: Failed to define pool default
error: operation failed: Storage source conflict with pool: 'images'
SOLVED:
virsh pool-list

Name State Autostart

images active yes

$ virsh pool-destroy images
Pool images destroyed

$ virsh pool-undefine images
Pool images has been undefined

Then restart the deployment

a reference to vagrant-libvirt README

storage_pool_name - Libvirt storage pool name, where box image and instance snapshots will be stored.

My Solution

Example: install boxe centos/7

• init Vagrant

vagrant init centos/7

• edit Vagrantfile config, in provider secition add config like follow:

Vagrant.configure("2") do |config|
  ...
  config.vm.provider :libvirt do |libvirt|
    libvirt.storage_pool_name = "images"
  end
  ...
end

• then, start install

vagrant up --provider libvirt

• (Option) if you like, you can add follow environment config to /etc/profile to make libvirt as default provider, then you not need --provider libvirt as vagrant parameter.

export VAGRANT_DEFAULT_PROVIDER=libvirt
