* qga-win: Enable 'can-offline' field in 'guest-get-vcpus' replySameeh Jubran2017-04-271-1/+1
| | | | | | | | | | | | | | | | | | | | The QGA schema states: @can-offline: Whether offlining the VCPU is possible. This member is always filled in by the guest agent when the structure is returned, and always ignored on input (hence it can be omitted then). Currently 'can-offline' is missing entirely from the reply. This causes errors in libvirt which is expecting the reply to be compliant with the schema docs.

* qga: Support enum names in guest-file-seekEric Blake2016-02-251-13/+6Star
| | | | | | | | | | | | | | | | | | Magic constants are a pain to use, especially when we run the risk that our choice of '1' for QGA_SEEK_CUR might differ from the host or guest's choice of SEEK_CUR. Better is to use an enum value, via a qapi alternate type for back-compatibility. With this, {"command":"guest-file-seek", "arguments":{"handle":1, "offset":0, "whence":"cur"}} becomes a synonym for the older {"command":"guest-file-seek", "arguments":{"handle":1, "offset":0, "whence":1}} Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

* qga: Better mapping of SEEK_* in guest-file-seekEric Blake2015-11-261-1/+19
| | | | | | | | | | | | | | | | | | | | Exposing OS-specific SEEK_ constants in our qapi was a mistake (if the host has SEEK_CUR as 1, but the guest has it as 2, then the semantics are unclear what should happen); if we had a time machine, we would instead expose only a symbolic enum. It's too late to change the fact that we have an integer in qapi, but we can at least document what mapping we want to enforce for all qga clients (and luckily, it happens to be the mapping that both Linux and Windows use); then fix the code to match that mapping. It also helps us filter out unsupported SEEK_DATA and SEEK_HOLE. In the future, we may wish to move our QGA_SEEK_* constants into qga/qapi-schema.json, along with updating the schema to take an alternate type (either the integer, or the string value of the enum name) - but that's too much risk during hard freeze.

| | | | | | | | | | | | | | | | | | Set fd non-blocking to avoid common use cases (like reading from a named pipe) from hanging the agent. This was missed in the original code. The patch introduces qemu_set_handle_nonoblocking, the local analog of qemu_set_nonblock for HANDLES. The usage of handles in qemu_set_non/block is impossible, because for win32 there is a difference between file discriptors and file handles, and all file ops are made via Win32 api.

| | | | | | | | | | | | | | | | | | | | | | | | | | | PCIAddress inforfation is obtained via SetupApi, which provides the information about address, bus, etc. We look throught entire device tree in the system and try to find device object for given volume. For this PDO SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration for a given devicei if it is possible. This is the most convinient way for a userspace service. The lookup is performed for every volume available. However, this information is not mandatory for vss-provider. In order to use SetupApi we need to notify linker about it. We do not need to install additional libs, so we do not make separate configuration option to use libsetupapi.su SetupApi gives as the same information as kernel driver with IRP_MN_QUERY_INTERFACE. https://support.microsoft.com/en-us/kb/253232 Signed-off-by: Olga Krishtal <okrishtal@virtuozzo.com> Signed-off-by: Denis V.

* qga: added mountpoint and filesystem type for single volumeOlga Krishtal2015-07-081-1/+53
| | | | | | | | | | | | | | | | | | | | | We should use GetVolumeXXX api to work with volumes. This will help us to resolve the situation with volumes without drive letter, i.e. when the volume is mounted as a folder. Such volume is called mounted folder. This volume is a regular mounted volume from all other points of view. The information about non mounted volume is reported as System Reserved. This volume is not mounted and thus it is not writable. GuestDiskAddressList API is not used because operations are performed with volumes but no with disks. This means that spanned disk will be counted and handled as a single volume. It is worth mentioning that the information about every disk in the volume can be queried via IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.

It is not practical to provide a command at the QEMU level explicitly targetting administrator account password change only, since different guest OS have different names for the admin account. While UNIX systems use 'root', Windows systems typically use 'Administrator' and even that can be renamed. Higher level apps like OpenStack have the ability to figure out the correct admin account name since they have info that QEMU/libvirt do not. The command accepts either the clear text password string, encoded in base64 to make it 8-bit safe in JSON: $ echo -n "123456" | base64 MTIzNDU2 $ virsh -c qemu:///system qemu-agent-command f21x86_64 \ '{ "execute": "guest-set-user-password", "arguments": { "crypted": false, "username": "root", "password": "MTIzNDU2" } }' {"return":{}} Or a password that has already been run though a crypt(3) like algorithm appropriate for the guest, again then base64 encoded: $ echo -n '$6$n01A2Tau$e...snip...DfMOP7of9AJ1I8q0' | base64 JDYkb...snip...YT2Ey $ virsh -c qemu:///system qemu-agent-command f21x86_64 \ '{ "execute": "guest-set-user-password", "arguments": { "crypted": true, "username": "root", "password": "JDYkb...snip...YT2Ey" } }' NB windows support is desirable, but not implemented in this patch.

| | | | | | | | | | | Currently management softwares cannot know whether a qemu-ga command is supported or not on the running platform until they actually execute it. This patch disables unsupported commands at launch time of qemu-ga, so that management softwares can check whether they are supported from 'enabled' property of the result from 'guest-info' command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add command to get mounted filesystems information in the guest. The returned value contains a list of mountpoint paths and corresponding disks info such as disk bus type, drive address, and the disk controllers' PCI addresses, so that management layer such as libvirt can resolve the disk backends. For example, when `lsblk' result is: NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 1G 0 disk `-sdb1 8:17 0 1024M 0 part `-vg0-lv0 253:1 0 1.4G 0 lvm /mnt/test sdc 8:32 0 1G 0 disk `-sdc1 8:33 0 512M 0 part `-vg0-lv0 253:1 0 1.4G 0 lvm /mnt/test vda 252:0 0 25G 0 disk `-vda1 252:1 0 25G 0 part / where sdb is a SCSI disk with PCI controller 0000:00:0a.0 and ID=1, sdc is an IDE disk with PCI controller 0000:00:01.1, and vda is a virtio-blk disk with PCI device 0000:00:06.0, guest-get-fsinfo command will return the following result: {"return": [{"name":"dm-1", "mountpoint":"/mnt/test", "disk":[ {"bus-type":"scsi","bus":0,"unit":1,"target":0, "pci-controller":{"bus":0,"slot":10,"domain":0,"function":0}}, {"bus-type":"ide","bus":0,"unit":0,"target":0, "pci-controller":{"bus":0,"slot":1,"domain":0,"function":1}}], "type":"xfs"}, {"name":"vda1", "mountpoint":"/", "disk":[ {"bus-type":"virtio","bus":0,"unit":0,"target":0, "pci-controller":{"bus":0,"slot":6,"domain":0,"function":0}}], "type":"ext4"}]} In Linux guest, the disk information is resolved from sysfs. So far, it only supports virtio-blk, virtio-scsi, IDE, SATA, SCSI disks on x86 hosts, and "disk" parameter may be empty for unsupported disk types.

| | | | | | | | | | | | | | | If an array of mount point paths is specified as 'mountpoints' argument of guest-fsfreeze-freeze-list, qemu-ga will only freeze the file systems mounted on specified paths in Linux guests. Otherwise, it works as the same way as guest-fsfreeze-freeze. This would be useful when the host wants to create partial disk snapshots.

* qga: Clean up fragile use of error_is_set()Markus Armbruster2014-05-091-14/+24
| | | | | | | | | | | | | | | | | | | | Using error_is_set(ERRP) to find out whether a function failed is either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP may be null, because errors go undetected when it is. It's fragile when proving ERRP non-null involves a non-local argument. Else, it's unnecessarily opaque (see commit 84d18f0). The error_is_set(errp) in the guest agent command handler functions are merely fragile, because all chall chains (do_qmp_dispatch() via the generated marshalling functions) pass a non-null errp argument. Make the code more robust and more obviously correct: receive the error in a local variable, then propagate it through the parameter.

* qga: Don't require 'time' argument in guest-set-time commandMichal Privoznik2014-02-231-11/+23
| | | | | | | | | | | | | | | | | | As the description to the guest-set-time states, the command is there to ease time synchronization after resume. If guest was suspended for longer period of time, its system time can go off so badly, that even NTP refuses to set it. That's why the command was invented: to give users chance to set the time (not necessarily 100% correct). However, there's is no real need for us to require users to pass an arbitrary time. Especially if we can read the correct value from RTC (boiling down to reading host's time). Hence this commit enables logic: guest-set-time() == guest-set-time($now_from_rtc) Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
