4.339. virt-v2v 4.339.1. RHSA-2011:1615 - Low: virt-v2v security and bug fix update An updated virt-v2v package that fixes one security issue and several bugs is now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) associated with each description below. virt-v2v is a tool for converting and importing virtual machines to libvirt-managed KVM (Kernel-based Virtual Machine), or Red Hat Enterprise Virtualization. Security Fix CVE-2011-1773 Using virt-v2v to convert a guest that has a password-protected VNC console to a KVM guest removed that password protection from the converted guest: after conversion, a password was not required to access the converted guest's VNC console. Now, converted guests will require the same VNC console password as the original guest. Note that when converting a guest to run on Red Hat Enterprise Virtualization, virt-v2v will display a warning that VNC passwords are not supported. Note The Red Hat Enterprise Linux 6.2 perl-Sys-Virt update must also be installed to correct CVE-2011-1773 . Bug Fixes BZ# 665883 When converting a guest virtual machine (VM), whose name contained certain characters, virt-v2v would create a converted guest with a corrupted name. Now, virt-v2v will not corrupt guest names. BZ# 671094 There were numerous usability issues when running virt-v2v as a non-root user. This update makes it simpler to run virt-v2v as a non-root user. BZ# 673066 virt-v2v failed to convert a Microsoft Windows guest with Windows Recovery Console installed in a separate partition. Now, virt-v2v will successfully convert a guest with Windows Recovery Console installed in a separate partition by ignoring that partition. BZ# 694364 virt-v2v failed to convert a Red Hat Enterprise Linux guest which did not have the symlink "/boot/grub/menu.lst". With this update, virt-v2v can select a grub configuration file from several places. BZ# 694370 This update removes information about the usage of deprecated command line options in the virt-v2v man page. BZ# 696089 virt-v2v would fail to correctly change the allocation policy, (sparse or preallocated) when converting a guest with QCOW2 image format. The error message "Cannot import VM, The selected disk configuration is not supported" was displayed. With this update, allocation policy changes to a guest with QCOW2 storage will work correctly. BZ# 700759 The options "--network" and "--bridge" can not be used in conjunction when converting a guest, but no error message was displayed. With this update, virt-v2v will now display an error message if the mutually exclusive "--network" and "--bridge" command line options are both specified. BZ# 702007 virt-v2v failed to convert a multi-boot guest, and did not clean up temporary storage and mount points after failure. With this update, virt-v2v will prompt for which operating system to convert from a multi-boot guest, and will correctly clean up if the process fails. BZ# 707261 virt-v2v failed to correctly configure modprobe aliases when converting a VMware ESX guest with VMware Tools installed. With this update, modprobe aliases will be correctly configured. BZ# 727489 When converting a guest with preallocated raw storage using the libvirtxml input method, virt-v2v failed with the erroneous error message "size(X) < usage(Y)". This update removes this erroneous error. BZ# 708961 When converting a Red Hat Enterprise Linux guest, virt-v2v did not check that the Cirrus X driver was available before configuring it. With this update, virt-v2v will attempt to install the Cirrus X driver if it is required. BZ# 732421 VirtIO systems do not support the Windows Recovery Console on 32-bit Windows XP. The virt-v2v man page has been updated to note this. On Windows XP Professional x64 Edition, however, if Windows Recovery Console is re-installed after conversion, it will work as expected. BZ# 677870 Placing comments in the guest fstab file by means of the leading "#" symbol caused an "unknown filesystem" error after conversion of a guest. With this update comments can now be used and error messages will not be displayed. Users of virt-v2v should upgrade to this updated package, which fixes these issues and upgrades virt-v2v to version 0.8.3.
