OK, subject says using guestmount. I'm surprised the slowdown isn't more than 95%. It's using FUSE which goes through an insane number of layers, see the "Update&q...

I can mount qcow2 img to nbd devices through guestfish or qemu-nbd I'm curious about which performance is better?

I create a *4x256GB-SSD RAID0(/dev/md1)* and I test the performance through fio. fio config: ioengine=libaiodirect=1time_basedruntime=120ramp_time=30size=100g The sequential read/write performance is: > > *read: 2000MB/swrite: 1800MB/s* Now I make a ext4 on the RAID0(/dev/md1) and mount on /home/. ANd I create a 100G-disk.qcow2 by guestfish. > $guestfish > ><fish>:

I followed the http://libguestfs.org/guestfs-building.1.html to build source. git clone https://github.com/libguestfs/libguestfs cd libguestfs ./autogen.sh make I installed the lib I didn't have it and everything is ok untill I enter *make* I got error message: > CCLD libguestfs.la > ar: `u' modifier ignored since `D' is the default (see `U') > make[3]:

I don't know why I can't register bugzilla so I post here. I have two ubuntu 16.04 machine A, B, and A install samba version 4.10.6, and B install version 4.3.11. I use samba-vfs in machine A. I mount share of A in B ex: sudo mount -t cifs -o username='ppp',password='admin' //IP/public /home/ppp/test And I found I can create file like $ touch test/yo But I can read/write

They do quite different things, they're not comparable. Can you specifically give the commands you are trying? We might be able to give more sensible...

I don't want prefix 'git' and I watched this http://libguestfs.org/guestfs-building.1.html#local-files . localenv ./autogen.sh \ -C \ --enable-werror \ "$@" but I cannot execute . localenv and I saw Note that *localenv* is included by the top Makefile (so it’s a Makefile fragment). But if it is also sourced by your *localconfigure* script then it is used as

I followed the guildline in http://libguestfs.org/guestfs-building.1.htm ./autogen.sh > make But I didn't see any executable file. I only see /fish/guestfish and /bash/guestfish the first one seems like a script.
