<DIV><FONT size=2 face=Arial>But i am saying that if the images of the VMs are
in a file system and not in a partition LVM of block of disks, may be that
change the "io=native" to "io=threads" give us more speed access of disk
in input/output</FONT></DIV>
<DIV><FONT face=Arial><FONT size=2></FONT></FONT> </DIV>
<DIV><FONT face=Arial><FONT size=2>And as in mode native "PVE" use a file system
as storage, may be convenient that pve-manager see if the image of the VM is in
a file system or is in a partition of blocks of disks (that is possible
with a VG of LVM partition), and depending of this condition, what IO
should use pve-manager to raise KVM and gain more speed of access
disk</FONT></FONT></DIV>
<DIV><FONT face=Arial><FONT size=2></FONT></FONT> </DIV>
<DIV><FONT face=Arial><FONT size=2>But as I have not tried it yet, I can not
confirm that this change will be appropriate.</FONT></FONT></DIV>
