* Don't attempt to call vm_remove() with a NULL vm: some functions likereyk2016-11-221-6/+7
| | | | | | config_getvm() already removed the vm on failure! Found by mlarkin@

* Insert disabled VMs into vmd(8)'s queues and allow vmctl(8) to display them.edd2016-11-223-9/+50
| | | | | | | | Tested by Jon Bernard and reyk@. OK reyk@, no objections mlarkin@. Thanks

| | | | | | | Brings us one step closer to having disabled by default vms is vm.conf(5), which can be started with vmctl(8). Input, testing and OK reyk@. Thanks.
* vmd(8)/vmctl(8) for i386. Some ugliness in #ifdef __i386__ areas will bemlarkin2016-10-266-10/+54
| | | | | | | | fixed in tree, but the changes required were pretty minimal. Note that i386 hosts are still presently limited to running i386 guests. ok deraadt, stefan, jca
* some readability fixes for the SWITCH CONFIGURATION section,jmc2016-10-201-14/+27
| | | | | | from edd barrett; while here, there seems to be three sections to the config file, not two;
* When the guest OS gets a zero MAC address on a network interface, it shouldreyk2016-10-182-12/+25
| | | | | | | | | | create a randomized locally administrated address. OpenBSD as a guest OS does this correctly but we cannot rely on it for other guests, so randomize the MAC address in vmd(8) on the host side if it is not specified by the user. I incremented the prefix by one to differentiate from the ones that are generated by OpenBSD in the kernel; fe:e1:bb:xx:xx:xx. OK deraadt@ mlarkin@
* Add the option to specify an interface group per virtual switch as well;reyk2016-10-175-18/+52
| | | | | | this group will be added to all VM tap(4) interfaces in the switch. Tested by martijn@
* Prefer memcpy/memmove over bcopyguenther2016-10-161-2/+2
| | | | ok mlarkin@
* Allow to add an interface to an interface group; with the group keyword.reyk2016-10-156-9/+89
| | | | Requested and tested by martijn@
* Fix functionality and semantics of vmctl load/reload/reset.reyk2016-10-124-21/+42
| | | | OK rzalamena@
* For correctness, always save errno when doing additional actionsreyk2016-10-121-8/+11
| | | | | | before printing it. OK rzalamena@
* The error case checks for saved_errno, set it accordinglyreyk2016-10-121-2/+2

* Allow 4 vio(4) interfaces in each VM. Also fix a bad interrupt assignment thatmlarkin2016-10-125-24/+43
| | | | | | | caused IRQ9 to be shared between the second disk device and the vio(4)s, which caused poor network performance. ok reyk, stefan
* Sync proc.c file vmd(8) and switchd(8).rzalamena2016-10-111-78/+90
| | | | | | | | | New changes: * Fix msgbuf_write() usage idiom; * Add context (function name) that fatal()ed; * Use less fds on startup; ok mlarkin@, reyk@
* Enable pledge(2) in vmm and the VM processes: This way the VMs andreyk2016-10-061-8/+3
| | | | | | | | | | | their monitor run in a very restricted environment. VMs only pledge "stdio vmm" which allows them to do most basic functions and a subset of vmm ioctls (the other part of vmm ioctls are only permitted in the parent). This requires the previous change in the vmm kernel part. OK mlarkin@

* Call setsid() to create a new session for the executed processes.reyk2016-10-051-1/+5

* Add a new "priv" process that is responsible for ioctls and restrictedreyk2016-10-048-34/+282
| | | | | | | | | | | operations that aren't allowed under pledge. This is a companion to the "vmd" process that runs as root but with pledge. With the "priv" process, each new tap(4) interface now gets a description to indicate the vm, eg. "vm1-if0-myvm". For network configuration will be done by vmd/priv later. OK mlarkin@

* As vmm(4) can now exit to vmd at any time to process pending interrupts,mlarkin2016-09-031-3/+5
| | | | | | | | | don't kill the VM if we are presented with an exit type that is not something we directly need to handle. Instead, simply re-enter the guest, possibly injecting an interrupt along the way. Still exit the process if presented with a triple fault, until we implement reboot support. ok stefan@

* Make error handling in config_getvm() more robuststefan2016-09-031-15/+62
| | | | | | | | | | | Open all fds first before sending messages to the vmm process. This prevents some intermediate state from being generated that will confuse vmm if it gets further messages. Also make sure that vmctl gets the right error reason later by saving errno upon a failure. ok reyk@ mlarkin@
* Process incoming com data asynchronously to running VCPUstefan2016-09-023-90/+167
| | | | | | | This registers a handler with libevent that is triggered on incoming data on the com port. ok mlarkin@
* Process incoming host->guest packets asynchronously to running VCPUstefan2016-09-022-5/+96
| | | | | | | | This registers a handler with libevent that is called on incoming packets for the guest. If they cannot be handled immediately (because the virtq is full), make sure they are handled on VCPU exits. ok mlarkin@
* Move event handling to separate threadstefan2016-09-022-30/+154
| | | | | | | | | That allows the main thread to handle the termination of a VM on reboot/shutdown or normal exit. The way it works is that VCPUs that terminate for some reason communicate this to a main thread that takes care of shutdown. ok mlarkin@

* Fix 2 minor issues and a typo in a comment in the pci emulation subsystem.mlarkin2016-09-011-5/+22
| | | | | | The first issue caused trash to be returned from an i/o port read where that port was unclaimed by any emulated device. The second issue caused improper BAR sizes to be reported for unassigned device BARs.
