2011-11-17monitor: Fix file_completion() to check for stat() failureMarkus Armbruster1-2/+2
stat() can fail for a file name just read with readdir(). Easiest way to trigger is a dangling symbolic link --- look ma, no race! When it fails, file_completion() uses sb.st_mode uninitialized. If the directory bit happens to be set, it appends a "/" to the completed name. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-11-01Sort the help info shown in monitor at runtimeWayne Xia1-4/+26
This patch would try sort the command list in monitor at runtime. As a result, command help and help info would show a more friendly sorted command list. For eg: (qemu)help acl_add acl_policy acl_remove acl_reset acl_show balloon block_passwd ... the command list is sorted. v3: using qsort function to sort the command list.

2011-10-27Monitor: do_info(): Drop QMP command handling codeLuiz Capitulino1-31/+1
Previous commits converted all existing QMP commands to the QAPI, now each info command does its own QMP call. Let's then drop all QMP command handling code from do_info(). Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-10-27QMP: Drop the query commands dispatch tableLuiz Capitulino1-58/+5
Because QMP development originated in the monitor, it has inherited the monitor's distinction between query- and non-query commands. However, previous commits unified both commands and the distinction is gone. This commit drops the query commands dispatch table and does some simplifications along the way.

2011-10-27qapi: Convert query-pciLuiz Capitulino1-10/+1
This also fixes a bug with the old version: QMP would invert device id and vendor id. This would look ok on HMP because it was printing "device:vendor" instead of "vendor:device". Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-10-27qapi: Convert query-balloonLuiz Capitulino1-12/+1
Please, note that some of the code supporting memory statistics is still around (eg. virtio_balloon_receive_stats() and reset_stats()). Also, the qmp_query_balloon() function is synchronous and thus doesn't make any use of the (not fully working) monitor's asynchronous command support (the old non-qapi implementation did).

2011-10-27qapi: Convert query-vncLuiz Capitulino1-10/+1
There are three important remarks in relation to the non-qapi command: 1. This commit also fixes the behavior of the 'query-vnc' and 'info vnc' commands to return an error when qemu is built without VNC support (ie. --disable-vnc). The non-qapi command would return the OK response in QMP and no response in HMP 2. The qapi version explicitly marks the fields 'host', 'family', 'service' and 'auth' as optional. Their are not documented as optional in the non-qapi command doc, but they would not be returned if vnc support is disabled. The qapi version maintains the same semantics, but documents those fields correctly 3. The 'clients' field, which is a list, is marked as optional but is always returned. If there are no clients connected an empty list is returned. This is not the Right Way to this in the qapi but it's how the non-qapi command used to work Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2011-10-11block: Keep track of devices' I/O statusLuiz Capitulino1-0/+6
This commit adds support to the BlockDriverState type to keep track of devices' I/O status. There are three possible status: BDRV_IOS_OK (no error), BDRV_IOS_ENOSPC (no space error) and BDRV_IOS_FAILED (any other error). The distinction between no space and other errors is important because a management application may want to watch for no space in order to extend the space assigned to the VM and put it to run again. Qemu devices supporting the I/O status feature have to enable it explicitly by calling bdrv_iostatus_enable() _and_ have to be configured to stop the VM on errors (ie. werror=stop|enospc or rerror=stop). In case of multiple errors being triggered in sequence only the first one is stored. The I/O status is always reset to BDRV_IOS_OK when the 'cont' command is issued. Next commits will add support to some devices and extend the query-block/info block commands to return the I/O status information.

Next commit will convert the query-status command to use the RunState type as generated by the QAPI. In order to "transparently" replace the current enum by the QAPI one, we have to make some changes to some enum values. As the changes are simple renames, I'll do them in one shot. The changes are: - Rename the prefix from RSTATE_ to RUN_STATE_ - RUN_STATE_SAVEVM to RUN_STATE_SAVE_VM - RUN_STATE_IN_MIGRATE to RUN_STATE_INMIGRATE - RUN_STATE_PANICKED to RUN_STATE_INTERNAL_ERROR - RUN_STATE_POST_MIGRATE to RUN_STATE_POSTMIGRATE - RUN_STATE_PRE_LAUNCH to RUN_STATE_PRELAUNCH - RUN_STATE_PRE_MIGRATE to RUN_STATE_PREMIGRATE - RUN_STATE_RESTORE to RUN_STATE_RESTORE_VM - RUN_STATE_PRE_MIGRATE to RUN_STATE_FINISH_MIGRATE Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2011-09-15HMP: info status: Print the VM stateLuiz Capitulino1-0/+6
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>

2011-09-15Monitor/QMP: Don't allow cont on bad VM stateLuiz Capitulino1-0/+5

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>

Test against RSTATE_IN_MIGRATE instead.

2011-09-15Replace the VMSTOP macros with a proper state typeLuiz Capitulino1-2/+2
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>
