Sun4c and Sun4d architectures and related CPUs are not fully implemented (especially Sun4c MMU) and there has been no interest for them. Likewise, a few CPUs (Cypress, Ross etc) are only half implemented. Remove the machines and CPUs, they can be re-added if needed later. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2013-04-15block: ssh: Use libssh2_sftp_fsync (if supported by libssh2) to flush to disk.Richard W.M. Jones1-5/+10
libssh2_sftp_fsync is an extension to libssh2 to support fsync(2) over sftp, which is itself an extension of OpenSSH. If both libssh2 and the ssh daemon support it, this will allow bdrv_flush_to_disk to commit changes through to disk on the remote server. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-04-15block: Add support for Secure Shell (ssh) block device.Richard W.M. Jones1-0/+49
qemu-system-x86_64 -drive file=ssh://hostname/some/image QEMU will ssh into 'hostname' and open '/some/image' which is made available as a standard block device. You can specify a username (ssh://user@host/...) and/or a port number (ssh://host:port/...). You can also use an alternate syntax using properties (file.user, file.host, file.port, file.path). Current limitations: - Authentication must be done without passwords or passphrases, using ssh-agent. Other authentication methods are not supported. - Uses a single connection, instead of concurrent AIO with multiple SSH connections. This is implemented using libssh2 on the client side. The server just requires a regular ssh daemon with sftp-server support. Most ssh daemons on Unix/Linux systems will work out of the box. Signed-off-by: Richard W.M.

2013-02-26qemu-log: default to stderr for logging outputPeter Maydell1-4/+4
Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.

2012-08-09iscsi: Pick default initiator-name based on the name of the VMRonnie Sahlberg1-0/+5
This patch updates the iscsi layer to automatically pick a 'unique' initiator-name based on the name of the vm in case the user has not set an explicit iqn-name to use. Create a new function qemu_get_vm_name() that returns the name of the VM, if specified. This way we can thus create default names to use as the initiator name based on the guest session. If the VM is not named via the '-name' command line argument, the iscsi initiator-name used wiull simply be iqn.2008-11.org.linux-kvm If a name for the VM was specified with the '-name' option, iscsi will use a default initiatorname of iqn.2008-11.org.linux-kvm:<name> These names are just the default iscsi initiator name that qemu will generate/use only when the user has not set an explicit initiator name via the commandlines or config files.

2012-08-03vnc: disable VNC password authentication (security type 2) when in FIPS modePaul Moore1-3/+5
FIPS 140-2 requires disabling certain ciphers, including DES, which is used by VNC to obscure passwords when they are sent over the network. The solution for FIPS users is to disable the use of VNC password auth when the host system is operating in FIPS compliance mode and the user has specified '-enable-fips' on the QEMU command line. This patch causes QEMU to emit a message to stderr when the host system is running in FIPS mode and a VNC password was specified on the commend line. If the system is not running in FIPS mode, or is running in FIPS mode but VNC password authentication was not requested, QEMU operates normally.

2012-08-02Support 'help' as a synonym for '?' in command line optionsPeter Maydell1-1/+1
For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. This change means that in some cases where we were being lazy in our string parsing, "?junk" will now be rejected as an invalid option rather than being (undocumentedly) treated the same way as "?". Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too.
