Is there any reason for the AMD SVM support to be not in place ?

No current effort to my knowledge.

Yeah, but I'd like to leave more memory for the host system, so I

Hi Dan,
Any ideas?
Just to confirm: your host system is an i7 3930k, which looks like a 6
core system. Should be plenty beefy enough for a 2 vCPU guest.
The issue you are seeing looks a bit like what happens when systems
are heavily oversubscribed and vCPUs can't get enough run time.
You can dump whole struct just a binary array(don't look into it in your
program), and get sizeof(vmxctx) via ioctl return. It should enough to
suspend/resume.
Then if AMD SVM mode will have different values on the structure, your
implementation won't break.
Does it make sense? Peter, Neel

I always wondered about virtualization environments which have pageable
guest memory - how does the guest kernel handle situations where it
really needs non-pageable memory? Does is simply not care because for
it the memory access looks just like it isn't paged but is simply very,
very slow?
For time-sensitive situations, there's not a lot of options other than
forcing guest memory to be wired, since there isn't visibility into the
host without having o/s-specific tools that could communicate this
information to the hypervisor.
Ok, that is how I understood it also, but I thought

Hi Andrea,
I was installing mysql56 in a freebsd10 inside freebsd 10 and while doing
the install the machine bombed out. In the console this is what I got:
Assertion failed: (aior != NULL), function ahci_handle_dma, file
/usr/src/usr.sbin/bhyve/pci_ahci.c, line 445.
Abort trap (core dumped)
Hi Andrea,
I just throw away at least one hour because I was running bhyvectl destroy
--vm=something instead of bhyvectl --destroy --vm=something. Bhyvectl just
silently ignored the wrong destroy instead of --destroy.
Maybe it's worth printing out something in such circumstances??? :-)

Hi Craig,
Can this flag be passed via bhyveload, and if so, how?
It can't yet: the API to userboot has to be changed to allow this to
be passed through.

Peter.

Hi Roman,
Currently bhyve(8) allows to specify either stdio or device path as a
TTY device. However, it could be useful to specify a TTY device by file
descriptor, e.g. when bhyve is being executed in an automated way by
other application, so a result of openpty(3) could be passed to it.
Hi Julian,
and allows fd to be a socket! :-)
Maybe not initially. There a bunch of code that wants to issue tty
ioctls on the fd, so the code currently verifies that it is indeed a tty.
later,
Peter.

Hi John,
1. I've read that virtualbox and bhyve cannot run at the same time. Is
this still the case? (because I've managed to start a bhyve instance
with virtualbox still running - is this a fluke?)
If you use VirtualBox with VT-x disabled, i.e. binary translation
mode, it will work.
Hi Steve,
The VM was building ports. I could try to deduce which ports, but I
wouldn't be 100% sure.
Probably no need, unless this can be repro'd by building that
particular port.
Some more questions: Were there other VMs running at the same time ?
What's the type of host CPU/number of
