I don't known how to do that in proxmox code (we use ioctl directly)
but
bad

Objet: [pve-devel] virtual scsi disk passed with scsi-block with lvm host
storage (wrong)
Hi, users have reported bugs with virtio-scsi + lvm host storage
https://forum.proxmox.com/threads/problem-with-iscsi-virtio-ovmf.26192/#post-131416
https://forum.proxmox.com/threads/lvm-and-virtio-scsi-detects-volume-as-complete-drive.24190/
currently we use scsi-block for lvm disk, insteda scsi-generic
I think this redhat bugzilla is related
https://bugzilla.redhat.com/show_bug.cgi?id=1179577
We need to fix something here in QemuServer.pm,
I think the ioctl don't detect correctly lvm, so maybe a workaround is needed
(bypass if $scfg->{type} eq 'lvm' ?)
if (my $info = path_is_scsi($path)) {
if ($info->{type} == 0) {
$devicetype = 'block';
} elsif ($info->{type} == 1) { # tape
$devicetype = 'generic';
}
}
