VirtualBox & X11: Guest console does not display remotey anynmore
Hi, since yesterday I have a weird problem. I cannot display VirtualBox _guest_ consoles remotely anymore (the GUI for configuration works). It worked two weeks ago and I am not aware of any changes. I am running Virtualbox headless on a server but use the GUI for installs when needed. I forward ssh (-X) and use "su -m" to keep the DISPLAY environment variable(DISPLAY=localhost:10.0) and xauth. Two weeks ago I did just that, 1. started "VirtualBox", 2. created a VM and a disk, 3. attached an ISO disk 4. pressed start and the "BIOS" appeared Yesterday it all goes up to step 3- just 4 does not work. I get an error instead of the BIOS screen, and on the server I get: X11 connection rejected because of wrong authentication. I checked all variables and parts - nothing has changed since the last install that worked a fortnight ago. Same kernel, same VirtualBox, same xauth, same desktop. # uname -a FreeBSD DellT620one.vv.fda 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r273569: Fri Oct 24 14:43:34 AEDT 2014 r...@dellt410two.vv.fda:/usr/obj/usr/src/sys/IPSEC amd64 # pkg info | grep virtual virtualbox-ose-4.3.18 General-purpose full virtualizer for x86 hardware virtualbox-ose-kmod-4.3.18 VirtualBox kernel module for FreeBSD The desktop Oracle Linux 6.5. I used this on the 28th of October successfully. No fresh installs/upgrades since, I believe. I can open X11 clients remotely (e.g. the VirtualBox control GUI works - just not the guest console) Do you have any ideas what could go wrong?

won't work like that, you would need to make sure the directories for
dependencies are there too :o)
Tried to do this with a full ports tree and I stopped it after gcc
started to build.
BTW: You need /usr/src available for the creation of the package.
Preferably matching the kernel you want to install it..
I do this regularly (but without VIMAGE) in a jail where I build all my
packages. ("make install" and "pkg create" in a script)
I do all updates from source. I only update kernel, user land and
ports when security is at risk. Usually independent from each other.
But VirtualBox is an exception. I update kernel and VirtualBox at the same
time.
I was not brave enough to enable VIMAGE and VirtualBox on the same server.
But I may do that soon. I plan a major reconfiguration ca. end of the
year. I hope it is stable enough.

Peter

VirtualBox performance
Hi all, I am running VirtualBox on a new server (a Dell T620). Inside is Oracle Linux. I run a Java app and it is very slow to start. Memory should not be an issue. I have 32 GB and 8 GB for the VM. The server has 2 Xeon CPUs with 4 core each (hypertthreated so VBox sees 16 CPUs). I do not see any difference between using 1 CPU or 16 for the VM.. Interestingly all the host CPUs are 60-70% in system calls when I run it on 16 CPUs, according to top. I am tempted to experiment with CPU sets, btw. I wonder whether VirtualBox and multiple CPUs are a good mix at all.. Do you have any recommendations how to speed up my VM and Java?

Re: RFC: Enabling VIMAGE in GENERIC

VIMAGE makes jails even better by allowing per-jail network stacks. I am using jails and VIMAGE for ca. 4 years, btw. On the other side of the fence (see Linux) containers became quite popular with Docker and are also used for process management and separation (systemd e.g.) Just to add this as a motivation for using jails and possibly VIMAGE, from a sysadmin perspective.

Re: Can a host OS user process create a zillion BHyVe VM:s and microcontrol them?

You could use jails.. - The kernel is booted in zero seconds;-), - you could use nullfs mounts to create a read-only filesystem tree - have one location read-write for your result - use a devfs mount for needed device nodes (see rule set 4) - and than run the command in a simple jail (directly from command line). - Afterwards you delete the mounts. Well, in fact you could prepare many many read-only jail file system trees and reuse them for the jail command again and again (minus the read-writre area for the output) It has much less overhead than starting a VM every time, I guess.

Virtualbx and CPU counting
Hi, I have a question: I have a server with - 2 Xeon E5-2609, - 4 cores each - 4 threads per core On OS level, Linux and FreeBSD see 8 processors. VirtualBox offers 16 CPUs as the maximal number for a VM. I expected 32. How does this work?

Re: Virtualbox and CPU counting
P.S. More precisly, I expected VirtualBOx to see 8 or 32 CPUs. In the past it was virtual CPU= "real" thread number, if I remember correctly. How many you give to a VM is a different matter.

Re: available hypervisors in FreeBSD
Hi all, I read through an older threat I kept in my archive. It started like this: On Wed, 1 Apr 2015, Udo Rader wrote: As far as my homework digging revealed, FreeBSD supports four hypervisors: * bhyve * KVM * QEMU * VirtualBox .. and later Xen was mentioned. I ask myself which of the solutions are most mature at the moment and immediately usable in production. Reason is a potential company move from VMware ESXi/Centos(6/7) with some critical Windows 2008 and 2012 IIS/.NET applications) involved. While most of open source may go into FreeBSD jails, we have a few CentOS6/7 boxes with proprietary software we have to keep, as well as the Windows VMs to maintain (there is a long term effort to move them to Open Source too but the final migration of all may be years away). We may phase out ESXi gradually, or just keep it, depending on the performance and maturity of FreeBSD based solutions. I have experience with Linux on VirtualBox and it worked well if the load was not high but the performance wasn't too good when under stress (but it never crashed, I might add). Which of the solutions are worth testing? Do you have recommendations? I am thinking of server software and "containerisation" only, so USB passthrough or PCI etc. is not really important. Stability, performance and resource utilisation (e.g. possible over-allocation of RAM) are matter most.
