Hello Denis!

Thank you very much for answering quickly. the strange thing is that I
have another OS installed ubuntu 12 x 32 works perfectly. The strange
thing is that I strip x64 error on reading ..

Here I spend my fstab settings of the VM

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/xvda2 during installation
UUID=f92edea0-9926-4435-83c9-f384945e7f38 /               ext4
errors=remount-ro 0       1
# swap was on /dev/xvda1 during installation
UUID=16630014-cb63-4f0a-b208-f262384e38fa none            swap    sw
           0       0


I put in fstab UUID = f92edea0-9926-4435-83c9-f384945e7f38

as I saw in the forum settings should be given as follows:?

/dev/xvda1        /        ext4      errors=remount-ro,barrier=0      0     1

instead of
UUID=f92edea0-9926-4435-83c9-f384945e7f38 /               ext4
errors=remount-ro 0       1


Swap it would also have to change it?
I have little experience in these settings, you have to put my foot,
so I will throw up a milestone in the ears.
thank you very much for your help

Ricardo
