curl error 22

Description of problem:
[RFE]Should give a better description about 'curl error 22' when failed using ssh identity http url at p2v client


Version-Release number of selected component (if applicable):
virt-p2v-1.32.5-2.el7.iso
virt-v2v-1.32.5-2.el7.x86_64
libguestfs-1.32.5-2.el7.x86_64



How reproducible:
100%

Steps to Reproduce:
1.Check ssh identity info at virt-p2v manual page
#man virt-p2v
SSH IDENTITIES

SSH identity downloaded from a website. In the GUI, use:

 │          Password: [    <leave this field blank>       ] │
 │                                                          │
 │  SSH Identity URL: [https://internal.example.com/id_rsa] │

or on the kernel command line:

 p2v.identity=https://internal.example.com/id_rsa

Anyone could still download the private key and use it to log in to the virt-v2v conversion server, but you could provide some extra security by configuring the web server to only allow connections from P2V machines.


2.Create a key pair which must have an empty passphrase and let public key append to the authorized_keys file at conversion server 

2.1#ssh-keygen -t rsa -N '' -f id_rsa

2.2#scp id_rsa.pub /root/.ssh/authorized_keys

3.Put the id_rsa at available website, such as http://pan.baidu.com/s/1qXFPzZm, 

4.Boot the machine into p2v client via iso

5.At inputting conversion server info interface, input conversion ip and username and then input id_rsa http url at ssh identity url, then the connection failed with error: curl error 22, pls refer to screenshot 'curl error 22', but the failed reason is not very clear
 


Actual results:
As above description

Expected results:
Should give a better description about 'curl error 22' when failed to use ssh identity http url to connect conversion server at p2v client
