Subject: [PATCH] input/ssh: Use nbdinfo --can connect (instead of --size)
|
||
|
|
|
||
|
|
nbdinfo --size prints the size on stdout, causing it to appear in
|
||
|
|
virt-v2v output. Using --can connect instead is silent.
|
||
|
|
|
||
|
|
Note that nbdinfo --can connect was added in libnbd 1.9.2 (Jul 2021)
|
||
|
|
and our previous minimum version of libnbd was 1.9.3 so we're OK.
|
||
|
|
However since neither of these was a stable version I also updated the
|
||
|
|
minimum libnbd requirement to 1.10 (Sep 2021), and added a proper
|
||
|
|
check in ./configure
|
||
|
|
|
||
|
|
