2018-08-23Allow to boot CDROM-only VMs.Reyk Floeter
Pointed out by Jon Williams OK mlarkin@ kn@ ccardenas@
2018-07-29add missing markup and some minor tweaks; ok jmc@anton
2018-07-12The vmctl start -I option was changed to -t.Reyk Floeter
I committed the manpage but accidentally forgot the main.c part. OK ccardenas@
2018-07-12Allow to use configured/running VMs as templates for other VM instances.Reyk Floeter
This introduces new grammar and the -t optional in vmctl start. (For now, only root can create VM instances; but it is planned to allow users to create their own VMs based on permissions and quota.) OK ccardenas@ mlarkin@ jmc@
2018-07-11check string lengths in vm_startReyk Floeter
2018-07-11remove useless macro;Jason McIntyre
2018-07-11Add -w option to vmctl stop to wait for completion of VM termination.Reyk Floeter
Use it in /etc/rc.d/vmd accordingly. OK sthen@
2018-07-11Add -f option to vmctl stop to forcefully kill a VM.Reyk Floeter
This also fixes a bug in vmm_sighdlr where it might have missed forwarding the TERMINATE_EVENT to the vmd parent after a VM child died, leading to an abandoned VM in the vmd parent process. OK ccardenas@ mlarkin@ benno@ kn@
2018-07-04When a VM stop request fails, set errno prior to calling warn() in order toanton
display the correct error message. This is a pattern found elsewhere in vmctl. With input from deraadt@ and encouraged by mlarkin@

2018-02-26vmctl: clarify console error messageccardenas
Clear up ambiguous error message when attaching to a console fails as the vm id is not guaranteed to be populated. ok mlarkin@

2018-01-03Add initial CD-ROM support to VMD via vioscsi.ccardenas
* Adds 'cdrom' keyword to vm.conf(5) and '-r' to vmctl(8) * Support various sized ISOs (Limitation of 4G ISOs on Linux guests) * Known working guests: OpenBSD (primary), Alpine Linux (primary), CentOS 6 (secondary), Ubuntu 17.10 (secondary). NOTE: Secondary indicates some issue(s) preventing full/reliable functionality outside the scope of the vioscsi work. * If the attached disks are non-bootable (i.e. empty), SeaBIOS (vmd's default BIOS) will boot from CD-ROM. ok mlarkin@, jca@
2017-11-05Add minimal DHCP support to vmd's built-in DHCP/BOOTP server.Reyk Floeter
This fixes "local interface" mode with the udhcpc client. udhcpc, a DHCP client that is used by busybox and many embedded Linux distributions, does not support BOOTP which is the predecessor and a valid subset of DHCP. OK mlarkin@, Carlos Cardenas

2017-09-08vmctl: style cleanup - spaces vs tabs.Mike Larkin

OK mlarkin@, krw@. Thanks!
2017-09-01vmctl: -L option clarification in man pageMike Larkin
2017-08-31vmctl: change a feedback message displayed to the user from "terminatedMike Larkin
vm X" to "sent request to terminate vm X". vmctl/vmd have not forcibly terminated VMs in a while, we try to let vmmci(4) gracefully shutdown the VM, so "vmctl stop" commands are really requests to stop, not forced stops. The new message indicates that a shutdown is (possibly) in progress and not "complete".
2017-08-31vmd/vmctl: disallow use of block or character devices as disks in VMs.Mike Larkin
These don't work today and present the user with a confusing error message if an attempt is made to use them. This commit detects attempts to use block or character devices and if detected, presents the user with a better message. ok jasper From Carlos Cardenas, thanks!
2017-08-30remove use of PAGE_SIZE and #include <sys/param.h>Mike Larkin
ok deraadt
2017-08-29quarterly rescan of the tree: remove unneccessary sys/param.h, andTheo de Raadt
annotate the ones which are needed.
2017-08-18distinguish errors during vm launch and return different error codes toMike Larkin
vmctl so that it can display proper errors for "disk missing" and "bios missing" situations. Expands on an earlier idea/diff from jasper. ok jasper@, pd@, tedu@

2017-05-04Report error for vmctl commands that need root privileges.Reyk Floeter
specifically: vmctl (load|reload|reset|log) Reported by Christian Barthel
2017-04-19Add support for dynamic "NAT" interfaces (-L/local interface).Reyk Floeter
When a local interface is configured, vmd configures a /31 address on the tap(4) interface of the host and provides another IP in the same subnet via DHCP (BOOTP) to the VM. vmd runs an internal BOOTP server that replies with IP, gateway, and DNS addresses to the VM. The built-in server only ever responds to the VM on the inside and cannot leak its DHCP responses to the outside. Thanks to Uwe Werler, Josh Grosse, and some others for testing! OK deraadt@
2017-04-14Update a man page example to reflect recent changes.Mike Larkin
Spotted by Ilya Kaliman, thanks.
2017-04-06Do not expose vmm(4) VM IDs to the user, use vmd(8)'s IDs instead.Reyk Floeter
Each VM has two IDs: one from the kernel (vmm) and a different one from userland (vmd). The vmm ID is not consistent and incremented on every boot during runtimg of the host system. The vmd ID remains the same during the lifetime of a configured VM, even after reboots. Configured VMs will even get and keep their IDs when the configuration is loaded. This is more what users expect. Pointed out and tested by otto@ OK deraadt@
2017-03-30Set interface flag to VMIFF_UP when using -i option. This way vmd will makeClaudio Jeker
sure the interfaces are up on startup. OK deraadt@, reky@
2017-03-25Boot using BIOS from /etc/firmware/vmm-bios by default.Reyk Floeter
Instead of using the internal "vmboot", VMs will now be booted using the external BIOS firmware in /etc/firmware/vmm-bios (which is subject to a LGPLv3 license). Direct booting of OpenBSD kernels or non-default BIOS images is still supported for now using the -b/boot option that is replacing the -k/kernel option. As requested by Theo, vmd(8) fails if neither the default BIOS is found nor a kernel has been specified in the VM configuration. The "vmm" BIOS has to be installed using fw_update(1), which will be done automatically in most cases where the OpenBSD can fetch it after install/upgrade. OK mlarkin@
2017-03-15Print "-" if the tty name is empty.Reyk Floeter
2017-03-03Undefined behavior: Variable 'user' was used as parameter andReyk Floeter
destination in snprintf(). Use a temporary variable instead. Found and OK by jsg@
2017-03-01Rename start_vm_complete to vm_start_complete for consistency.Reyk Floeter
2017-03-01unbreak vmctl build by renaming a function that now conflicts withMike Larkin
something from vmd.h . Temporary fix until the original committer can fix it the way he desires.
2017-03-01Add "owner" option to set a user/group ownership for pre-configured VMsReyk Floeter
This allows matching users to start or stop VMs that they "own" and to access the console accordingly. OK mlarkin@
