2011-09-15HMP: info status: Print the VM stateLuiz Capitulino
Today our printf format for the "info status" command is: VM status: %s Where the string can be "running", "running (single step mode)" or "paused". This commit extends it to: VM status: %s (%s) The second string corresponds to the "status" field as returned by the query-status QMP command and it's only printed if "status" is not "running" or "paused". Example: VM status: paused (shutdown) PS: libvirt uses "info status" when using HMP, but the new format should not break it. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-09-15QMP: query-status: Introduce 'status' keyLuiz Capitulino

2011-09-15Monitor/QMP: Don't allow cont on bad VM stateLuiz Capitulino
We have two states where issuing cont before system_reset can cause problems: RSTATE_SHUTDOWN (when -no-shutdown is used) and RSTATE_PANICKED (which only happens with kvm). This commit fixes that by doing the following when state is RSTATE_SHUTDOWN or RSTATE_PANICKED: 1. returning an error to the user/client if cont is issued 2. automatically transition to RSTATE_PAUSED during system_reset Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2011-09-15Drop the incoming_expected global variableLuiz Capitulino
Test against RSTATE_IN_MIGRATE instead. Please, note that the RSTATE_IN_MIGRATE state is only set when all the initial VM setup is done, while 'incoming_expected' was set right in the beginning when parsing command-line options. Shouldn't be a problem as far as I could check. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-09-15Replace the VMSTOP macros with a proper state typeLuiz Capitulino
Today, when notifying a VM state change with vm_state_notify(), we pass a VMSTOP macro as the 'reason' argument. This is not ideal because the VMSTOP macros tell why qemu stopped and not exactly what the current VM state is. One example to demonstrate this problem is that vm_start() calls vm_state_notify() with reason=0, which turns out to be VMSTOP_USER. This commit fixes that by replacing the VMSTOP macros with a proper state type called RunState. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2011-07-23Introduce a 'client_add' monitor command accepting an open FDDaniel P. Berrange
Allow client connections for VNC and socket based character devices to be passed in over the monitor using SCM_RIGHTS. One intended usage scenario is to start QEMU with VNC on a UNIX domain socket. An unprivileged user which cannot access the UNIX domain socket, can then connect to QEMU's VNC server by passing an open FD to libvirt, which passes it onto QEMU. { "execute": "get_fd", "arguments": { "fdname": "myclient" } } { "return": {} } { "execute": "add_client", "arguments": { "protocol": "vnc", "fdname": "myclient", "skipauth": true } } { "return": {} } In this case 'protocol' can be 'vnc' or 'spice', or the name of a character device (eg from -chardev id=XXXX) The 'skipauth' parameter can be used to skip any configured VNC authentication scheme, which is useful if the mgmt layer talking to the monitor has already authenticated the client in another way. * console.h: Define 'vnc_display_add_client' method * monitor.c: Implement 'client_add' command * qemu-char.c, qemu-char.h: Add 'qemu_char_add_client' method * qerror.c, qerror.h: Add QERR_ADD_CLIENT_FAILED * qmp-commands.hx: Declare 'client_add' command * ui/vnc.c: Implement 'vnc_display_add_client' method Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-04-01Parse SDR1 on mtspr instead of at translate timeDavid Gibson
On ppc machines with hash table MMUs, the special purpose register SDR1 contains both the base address of the encoded size (hashed) page tables. At present, we interpret the SDR1 value within the address translation path. But because the encodings of the size for 32-bit and 64-bit are different this makes for a confusing branch on the MMU type with a bunch of curly shifts and masks in the middle of the translate path. This patch cleans things up by moving the interpretation on SDR1 into the helper function handling the write to the register. This leaves a simple pre-sanitized base address and mask for the hash table in the CPUState structure which is easier to work with in the translation path. This makes the translation path more readable. It addresses the FIXME comment currently in the mtsdr1 helper, by validating the SDR1 value during interpretation. Finally it opens the way for emulating a pSeries-style partition where the hash table used for translation is not mapped into the guests's RAM.

2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2011-02-01vnc: Fix password expiration through 'change vnc ""' (v2)Anthony Liguori
commit 52c18be9e99dabe295321153fda7fce9f76647ac introduced a regression in the change vnc password command that changed the behavior of setting the VNC password to an empty string from disabling login to disabling authentication. This commit refactors the code to eliminate this overloaded semantics in vnc_display_password and instead introduces the vnc_display_disable_login. The monitor implementation then determines the behavior of an empty or missing string. Recently, a set_password command was added that allows both the Spice and VNC password to be set. This command has not shown up in a release yet so the behavior is not yet defined. This patch proposes that an empty password be treated as an empty password with no special handling. For specifically disabling login, I believe a new command should be introduced instead of overloading semantics. I'm not sure how Spice handles this but I would recommend that we have Spice and VNC have consistent semantics here for the 0.14.0 release. Reported-by: Neil Wilson <neil@aldur.co.uk> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - Add a proper return to make sure that login is really disabled instead of relying on the VNC server to treat empty passwords specially
