is there anybody who knows how we can get child values using libxml (Reader class) def xml_import_to_brands require''xml'' reader = XML::Reader.file(''c:/brands.xml'') . . .

v1 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00047.html v2 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00051.html v3: - Back to using string/string_format and attribute/attribute_format. - Add both single_element and single_element_format. - Rebased and retested. Rich.

This is tangentially related to: https://bugzilla.redhat.com/show_bug.cgi?id=1372668 The problem in that bug is that we didn't pass the source CPU model (Sandybridge in that case) through to the target RHV hypervisor. So when the Windows guest booted on the target it gives an error about CPU hardware being disconnected (although it otherwise boots and works fine). This patch series

v1 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00047.html However it was broken in a few ways. First of all the documentation was broken because "/**" enhanced comments were not permitted on macros. This is fixed in the new 1/4 patch. Secondly we didn't use single_element() everywhere possible, which is fixed in the new 4/4 patch. Lastly I've

Consolidate and extend the use of funky start_element() etc macros. Rich.

v1 -> v2: - Support for passing topology through -o glance. - Support for passing topology through -o rhv. - Use bool for acpi/apic/pae struct fields in virt-p2v. - Write the xpath expression in error messages instead of file/line. - Fix more memory leaks in virt-p2v cpuid.c. - Passes make check & check-valgrind. There may be some other minor changes. I believe that everything

Hi, as it was already discussed on this list, here it is my attempt in splitting virt-p2v in an own repository. Sadly there are things that must be copied from libguestfs, as it cannot be avoided. The approach taken was to run a script (will send separately) to just get the "p2v" subdirectory with its history as own repository, and then add in few followup commits all the bits needed

Now that virt-p2v has its own repository [1] and releases [2], it is time to remove it from libguestfs.
