The source check of a new logical or NFS pool accepted only letters,
digits and "/", which refused paths such as /dev/mapper/vg0-data,
/dev/disk/by-id/wwn-..., /dev/disk/by-path/pci-0000:00:1f.2-ata-1 or
/export/vm_images. The target check let any first character but "-"
through, so a quote, "<" or "&" reached the pool XML and libvirt failed
on it.
Target and source now share one expression: letters, digits, "/", "_",
".", ":" and "-" (not first, not right after "/"), still in linear time.
The Vagrant computes' NFS export becomes /srv/wvc-nfs, created through the
page in the live pool test.
create_storage_netfs started the pool without a build, so a netfs pool
whose target directory was missing failed to mount ("mount point ... does
not exist"): the page showed the error and the pool stayed defined and
inactive. It now starts with VIR_STORAGE_POOL_CREATE_WITH_BUILD, as the
dir and logical pools do, which makes the mount point.
The Vagrant computes export /srv/wvcnfs to 127.0.0.1, and the live pool
test creates an NFS pool on it at a missing mount point when
TEST_LIBVIRT_NFS_EXPORT is set.
vagrant up makes a throwaway CA and a client certificate in
.vagrant/tls/.pki/libvirt with the host's openssl (Vagrant puts its own
first on PATH). Each compute signs its server certificate for its
address, asks for SASL over TLS like over TCP, and listens on 16514.
libvirt takes a client certificate from $HOME/.pki/libvirt, so the
README's second run uses HOME=.vagrant/tls with TEST_LIBVIRT_TYPE=3 and
leaves the user's own certificates alone.
The Vagrant computes serve a 1 GiB LUN on 127.0.0.1 (targetcli). A live
test, run with TEST_LIBVIRT_ISCSI_TARGET, starts a transient iSCSI pool
on it and attaches the LUN from the VM page to a stopped and a running
VM: both definitions get a raw block disk on its /dev/disk/by-path link.
libvirt's logical pool cannot change a volume's capacity, so every
resize of such a disk ended in a 500. Disks are resized one at a time;
VIR_ERR_NO_SUPPORT becomes a message naming the disk, and the other
disks still grow.
A live test creates an LVM pool from the storage page on a spare disk
(TEST_LIBVIRT_LVM_DEVICE; the Vagrant computes get /dev/vdb), attaches
new and existing volumes to stopped and running VMs as block disks, and
checks the refused resize in every state.
The Vagrantfile (Ubuntu 18.04, supervisor, a missing requirements file)
is replaced: two AlmaLinux 10 VMs with nested KVM, set up by the
bootstrap, with a SASL user for TCP and the host user's SSH key for
root, so the live suite, migration included, runs without real hosts.
The README's Running tests says what the host needs and how to run it.
The *migrations/* ignore rule is removed. appsettings, computes and
logs pin default_auto_field to AutoField, so makemigrations --check
reports no pending BigAutoField migrations and existing installs need
no schema change.
The Vagrant provisioning no longer runs makemigrations, which created
install-specific migration files that conflict with the committed
history; it only runs migrate.
