Bug ID: 192456
Summary: vt vt_vga graphical console very slow in XenServer,
VirtualBox
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
I tried booting with kern.vty=vt on Xen and VirtualBox to see what happens.
XenServer console is extremely slow, about 4-5 seconds to redraw the whole
screen each time a new line is printed, booting takes several minutes.
VirtualBox is slow, but not as bad, takes approx 1 second to redraw screen
(tolerable but not ideal).
I tried FreeBSD-11.0-CURRENT-amd64-20140804-r269497-disc1.iso as well as
snapshot isos of 10 and 11 from about a month ago (I didn't specifically check
age).
Setting hw.vga.textmode=1 restores normal speed like syscons. Would it be a
good idea to make the kernel default to textmode if kern.vm_guest isn't "none"?
