We already have virAsprintf, so picking a similar name helps for seeing a similar purpose. Furthermore, the prefix V before printf generally implies 'va_list', even though this variant was '...', and the old name got in the way of adding a new va_list version. global rename performed with: $ git grep -l virBufferVSprintf \ | xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g' then revert the changes in ChangeLog-old.
