Hello everyone,
I have been experiencing an extremely peculiar behaviour with my VM's running on Virtual Box. The host is Windows 7 machine, fresh install). I have a fresh VB install and fresh Ubuntu image 18.04. The settings are as follows:
4 CPU cores, PAE/NX enabled (I am running Intel Xeon E5 2640 v4 with 10 cores on the host)
4 GB of ram (out of 32 GB on host)
VT-x + Nested Paging enabled
50 GB fixed storage allocation, using SATA controller, HOST I/O cache enabled, "solid state drive" ticked (I have two 500 GB Samsung 850 Evo SSD's in AHCI mode on the host)
The problem is that it barely works. Every third time I try to boot it, it freezes on the "Ubuntu" loading screen, forcing me to power off the machine. When it boots, it's extremely slow. It's slow in a sense that when I type in a wrong command in the terminal, it takes ~30 seconds for the system to recognize the command as wrong and say "command not found". Using apt-get install fetches the files very quickly, but the unpacking part takes ages, maybe ~1 minute per a file to unpack, totaling in 20 minutes to install php5, which is a 25mb package. The GUI is very responsive. It seems like it's just any drive I/O operation is being slow. However, my I/O speed and usage tests say otherwise - I/O usage is at 0-1% in System Monitor. Running
gives "Timing cached reads" 9363 MB/sec, "Timing buffered disk reads" 1192 MB/sec.
I have tried reinstalling VB, reinstalling the host OS, creating a new image from scratch, importing an image. My friend has an identical hardware and software setup, he doesn't have this issue. It only started happening recently and I honestly have no idea about what's going on, I am out of ideas.
Any advice or suggestion is more than welcome!
P.S I am installing a new image right now, the minimal version has taken 4 hours so far, and it's still installing.. Is it a VB's or my system's fault?
