Description
I use VirtualBox 6.1 In Ubuntu 20.04 when I create a new virtual machine with SATA disk controller , but have not set the "Use Host I/O Cache" option (the default setting) if I intall a lot of debs, I will get very high disk I/O consumption at host machine, but have very very low disk throughput.
useing ittop, I find The reason is the jbd2 process blocking the disk access Maybe it is a bug !!!
