[Libguestfs] [PATCH 1/2] Allow reading more data than the reported size of a volume

If a volume is not an exact multiple of 512 bytes, qemu-img will report its size rounded down to a 512 byte boundary. However, when copying, the file is still read until EOF, which will return more data than was expected. This change prevents that causing a failure in itself. The situation is still not resolved, however, as there are still situations where this will cause a failure. For example, copying will fail writing to a block device if an attempt is made to write too much data. --- lib/Sys/VirtV2V/Connection/Source.pm | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/lib/Sys/VirtV2V/Connection/Source.pm b/lib/Sys/VirtV2V/Connection/Source.pm index 960aff3..8cbfe25 100644 --- a/lib/Sys/VirtV2V/Connection/Source.pm +++ b/lib/Sys/VirtV2V/Connection/Source.pm @@ -167,7 +167,7 @@ sub _volume_copy v2vdie __x('Didn\'t receive full volume.
