[Users] Unable to open pty

[Galia Lisovskaya]

Hi! I'm don't find bug traker on your company site, and try send bug
report for any your officer, sorry.

CentOS 5.4, your rpm:

Name        : vzdump                       Relocations: (not relocatable)
Version     : 1.2                               Vendor: Proxmox

Summary     : OpenVZ backup scripts
Description :
This package contains the vzdump script to backup and restore openvz images.

Does'nt work:

vzdump --snapshot 201
Can't locate PVE/VZDump.pm in @INC (@INC contains:
/usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl

at /usr/sbin/vzdump line 27.
BEGIN failed--compilation aborted at /usr/sbin/vzdump line 27.

And, old vzdump (vzdump-1.1-2) does'nt work if VG or LV has numbers in name:

[root at ovz01 ~]# vzdump --snapshot 201
INFO: Starting new backup job - vzdump --snapshot 201

  ovz01   1   4   0 wz--n- 454,09G 672,00M
[root at ovz01 ~]#

I think, it's bad regexp in get_lvm_device() or get_lvm_mapping.
Sorry, don't have skill of developing of Perl (i'm love Python and
bash :)) ), and don't may send patch.
