Similar to the chardev bit, ARM boards depend on the old style '-net nic' for actually instantiating net devices. But we can't block out -netdev altogether since it's needed for upcoming virtio support. And add tests for working ARM XML with console, disk, and networking.

This corresponds to '-sd' and '-drive if=sd' on the qemu command line. Needed for many ARM boards which don't provide any other way to pass in storage.

QEMU ARM boards don't give us any way to explicitly wire in a -chardev, so use the old style -serial options. Unfortunately this isn't as simple as just turning off the CHARDEV flag for qemu-system-arm, as upcoming virtio support _will_ use device/chardev.

On my machine, a guest fails to boot if it has a sound card, but not graphical device/display is configured, because pulseaudio fails to initialize since it can't access $HOME. A workaround is removing the audio device, however on ARM boards there isn't any option to do that, so -nographic always fails. Set QEMU_AUDIO_DRV=none if no <graphics> are configured. Unfortunately this has massive test suite fallout. Add a qemu.conf parameter nographics_allow_host_audio, that if enabled will pass through QEMU_AUDIO_DRV from sysconfig (similar to vnc_allow_host_audio)

Add an attribute named 'removable' to the 'target' element of disks, which controls the removable flag. For instance, on a Linux guest it controls the value of /sys/block/$dev/removable. This option is only valid for USB disks (i.e. bus='usb'), and its default value is 'off', which is the same behaviour as before. To achieve this, 'removable=on' (or 'off') is appended to the '-device usb-storage' parameter sent to qemu when adding a USB disk via '-disk'. A capability flag QEMU_CAPS_USB_STORAGE_REMOVABLE was added to keep track if this option is supported by the qemu version used.

virVMXFormatHardDisk() and virVMXFormatCDROM() duplicated a lot of code from each other and made a lot of nested if checks to build each part of the VMX file. This hopefully simplifies the code path while combining the two functions with no net difference.

Since virtlockd is only built when libvirtd is built, we should not install its auxiliary files unconditionally. This solves two failures. 1.

vhost only works in KVM mode at the moment, and is infact compiled out if the emulator is built for non-native architecture. While it may work at some point in the future for plain qemu, for now it's just noise on the command line (and which contributes to arm cli breakage).

FreeBSD 10 recently changed their definition of RAND_MAX, to try and cover the fact that their evenly distributed results of rand() really are a smaller range than a full power of 2. As a result, I did some investigation, and learned: 1. POSIX requires random() to be evenly distributed across exactly 31 bits. glibc also guarantees this for rand(), but the two are unrelated, and POSIX only associates RAND_MAX with rand(). Avoiding RAND_MAX altogether thus avoids a build failure on FreeBSD 10. 2. Concatenating random bits from a PRNG will NOT provide uniform coverage over the larger value UNLESS the period of the original PRNG is at least as large as the number of bits being concatenated. Simple example: suppose that RAND_MAX were 1 with a period of 2**1 (which means that the PRNG merely alternates between 0 and 1). Concatenating two successive rand() calls would then invariably result in 01 or 10, which is a rather non-uniform distribution (00 and 11 are impossible) and an even worse period (2**0, since our second attempt will get the same number as our first attempt). But a RAND_MAX of 1 with a period of 2**2 (alternating between 0, 1, 1, 0) provides sane coverage of all four values, if properly tempered. (Back-to-back calls would still only see half the values if we don't do some tempering). We therefore want to guarantee a period of at least 2**64, preferably larger (as a tempering factor); POSIX only makes this guarantee for random() with 256 bytes of info. * src/util/virrandom.c (virRandomBits): Use constants that are accurate for the PRNG we are using, not an unrelated PRNG. (randomState): Ensure the period of our PRNG exceeds our usage. Signed-off-by: NEric Blake <eblake@redhat.com>

Commit 29fe5d74 (released in 1.1.1) introduced a latent problem for any caller of virSecurityManagerSetProcessLabel and where the domain already had a uid:gid label to be parsed. Such a setup would collect the list of supplementary groups during virSecurityManagerPreFork, but then ignores that information, and thus fails to call setgroups() to adjust the supplementary groups of the process. Upstream does not use virSecurityManagerSetProcessLabel for qemu (it uses virSecurityManagerSetChildProcessLabel instead), so this problem remained latent until backporting the initial commit into v0.10.2-maint (commit c061ff5e, released in 0.10.2.7), where virSecurityManagerSetChildProcessLabel has not been backported. As a result of using a different code path in the backport, attempts to start a qemu domain that runs as qemu:qemu will end up with supplementary groups unchanged from the libvirtd parent process, rather than the desired supplementary groups of the qemu user. This can lead to failure to start a domain (typical Fedora setup assigns user 107 'qemu' to both group 107 'qemu' and group 36 'kvm', so a disk image that is only readable under kvm group rights is locked out). Worse, it is a security hole (the qemu process will inherit supplemental group rights from the parent libvirtd process, which means it has access rights to files owned by group 0 even when such files should not normally be visible to user qemu). LXC does not use the DAC security driver, so it is not vulnerable at this time. Still, it is better to plug the latent hole on the master branch first, before cherry-picking it to the only vulnerable branch v0.10.2-maint. * src/security/security_dac.c (virSecurityDACGetIds): Always populate groups and ngroups, rather than only when no label is parsed.

When using a <interface type="network"> that points to a network with hostdev forwarding mode a hostdev alias is created for the network. This allias is inserted into the hostdev list, but is backed with a part of the network object that it is connected to. When a VM is being stopped qemuProcessStop() calls networkReleaseActualDevice() which eventually frees the memory for the hostdev object. Afterwards when the domain definition is being freed by virDomainDefFree() an invalid pointer is accessed by virDomainHostdevDefFree() and may cause a crash of the daemon. This patch removes the entry in the hostdev list before freeing the depending memory to avoid this issue. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1000973

QEMU commit 3984890 introduced the "pci-hole64-size" property, to i440FX-pcihost and q35-pcihost with a default setting of 2 GB. Translate <pcihole64>x<pcihole64/> to: -global q35-pcihost.pci-hole64-size=x for q35 machines and -global i440FX-pcihost.pci-hole64-size=x for i440FX-based machines. Error out on other machine types or if the size was specified but the pcihost device lacks 'pci-hole64-size' property. https://bugzilla.redhat.com/show_bug.cgi?id=990418

<controller type='pci' index='0' model='pci-root'> <pcihole64 unit='KiB'>1048576</pcihole64> </controller> It can be used to adjust (or disable) the size of the 64-bit PCI hole. The size attribute is in kilobytes (different unit can be specified on input), but it gets rounded up to the nearest GB by QEMU. Disabling it will be needed for guests that crash with the 64-bit PCI hole (like Windows XP), see: https://bugzilla.redhat.com/show_bug.cgi?id=990418
