2014-09-20xen-hvm.c: Always return -1 when failure occurs in xen_hvm_init()Chen Gang
When failure occurs, it need to use "return -1" instead of exit(1), so an upper layer has a chance to print failure information, too. For simplicity, in xen_hvm_init(), also use '-1' instead of all '-errno', since all related upper callers always exit(1) on failure. It is not a normal function, it does not release related resources when return -1, so need give related comments for it. It passes common check: "./configure --enable-xen && make && make check" "echo $? == 0" Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Acked-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

When more than one is used, the terminal settings aren't restored correctly on exit. Fixable. However, such usage makes no sense, because the users race for input, so outlaw it instead.

2014-09-18pc: leave more space for BIOS allocationsMichael S. Tsirkin
Since QEMU 2.1, we are allocating more space for ACPI tables, so no space is left after initrd for the BIOS to allocate memory. Besides ACPI tables, there are a few other uses of high memory in SeaBIOS: SMBIOS tables and USB drivers use it in particular. These uses allocate a very small amount of memory. Malloc metadata also lives there. So we need _some_ extra padding there to avoid initrd breakage, but not much. John Snow found a case where RHEL5 was broken by the recent change to ACPI_TABLE_SIZE; in his case 4KB of extra padding are fine, but just to be safe I am adding 32KB, which is roughly the same amount of padding that was left by QEMU 2.0 and earlier. Move initrd to leave some space for the BIOS. Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reported-by: John Snow <jsnow@redhat.com> Signed-off-by: Michael S.

2014-09-18virtio-pci: fix migration for pci bus masterMichael S. Tsirkin
Current support for bus master (clearing OK bit) together with the need to support guests which do not enable PCI bus mastering, leads to extra state in VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version migration for the case when guests use the device before setting DRIVER_OK. Rip out VIRTIO_PCI_FLAG_BUS_MASTER_BUG and implement a simpler work-around: treat clearing of PCI_COMMAND as a virtio reset. Old guests never touch this bit so they will work. As reset clears device status, DRIVER and MASTER bits are now in sync, so we can fix up cross-version migration simply by synchronising them, without need to detect a buggy guest explicitly. Drop tracking VIRTIO_PCI_FLAG_BUS_MASTER_BUG completely. As reset makes the device quiescent, in the future we'll be able to drop checking OK bit in a bunch of places.

2014-09-18Revert "virtio: don't call device on !vm_running"Michael S. Tsirkin
This reverts commit a1bc7b827e422e1ff065640d8ec5347c4aadfcd8. virtio: don't call device on !vm_running It turns out that virtio net assumes that vm_running is updated before device status callback in many places, so this change leads to asserts. Previous commit fixes the root issue that motivated a1bc7b827e422e1ff065640d8ec5347c4aadfcd8 differently, so there's no longer a need for this change. In the future, we might be able to drop checking vm_running completely, and check vm state directly.

2014-09-18qdev: Move global validation to a single functionEduardo Habkost
Currently GlobalProperty.not_used=false has multiple meanings: * It may be a property for a hotpluggable device, which may or may not have been used by a device; * It may be a machine-type-provided property, which may or may not have been used by a device. * It may be a user-provided property that was actually not used by any device. Simplify the logic by having two separate fields: 'user_provided' and 'used'. This allows the entire global property validation logic to be contained in a single function, and allows more specific error messages.

we currently have the Nagle algorithm enabled for all outgoing VNC updates. This may delay sensitive updates as mouse movements or typing in the console. As we currently prepare all data in a buffer and then send as much as we can disabling the Nagle algorithm should not cause big trouble. Well established VNC servers like TightVNC set TCP_NODELAY as well. A regular framebuffer update request generates exactly one framebuffer update which should be pushed out as fast as possible.

2014-09-16util/qemu-sockets.c: Support specifying IPv4 or IPv6 in socket_dgram()Peter Maydell
Currently you can specify whether you want a UDP chardev backend to be IPv4 or IPv6 using the ipv4 or ipv6 options if you use the QemuOpts parsing code in inet_dgram_opts(). However the QMP struct parsing code in socket_dgram() doesn't provide this flexibility (which in turn prevents us from converting the UDP backend handling to the new style QAPI framework). Use the existing inet_addr_to_opts() function to convert the remote->inet address to option strings; this handles ipv4 and ipv6 flags as well as host and port. (It will also convert any 'to' specification, which is harmless as it is ignored in this context.)

2014-09-12qcow2: Add falloc and full preallocation optionHu Tao
preallocation=falloc allocates disk space by posix_fallocate(), preallocation=full allocates disk space by writing zeros to disk. Both modes imply preallocation=metadata.

2014-09-12block: round up file size to nearest sectorHu Tao
Currently the file size requested by user is rounded down to nearest sector, causing the actual file size could be a bit less than the size user requested. Since some formats (like qcow2) record virtual disk size in bytes, this can make the last few bytes cannot be accessed. This patch fixes it by rounding up file size to nearest sector so that the actual file size is no less than the requested file size.
