A fix for this issue (automatic resets not working in VMs) is in the esptool master branch and will be in IDF master soon.

In the meantime, you can do either one of two things:
- Manually hold down the "BOOT" button while flashing.
OR
- In "make menuconfig", "Serial Flasher Config" set "Before Flashing Config" to "Reset with ESP32R0 Windows Workaround"

(Originally this issue was reported and reproduced on Windows, but it can happen on VMs of any OS.)
