[PATCH] tests: switch away from HAVE_SOCKETPAIR
by Pino Toscano 19 Mar '20

19 Mar '20

Since the removal of gnulib, HAVE_SOCKETPAIR is no more defined, making these two tests effectively skipped. Use the same strategy used in other generic library bits, i.e. exclude the socketpair usage on Windows. Semi-related change in virnetdaemontest.c to make it build: since virutil.h does not include unistd.h anymore, we need to include it.

qemu:///embed and isolation from global components
by Andrea Bolognani 19 Mar '20

19 Mar '20

Recently I've been working on integrating qemu:///embed into an application. It's been reasonably smooth so far :) There's one thing, however, that has caused a bit of confusion, and I would like to clarify whether my expectations are incorrect, there are genuine bugs in the implementation that need to be addressed, or maybe the experimental nature of embedded driver support results in not all scenarios having yet been considered and catered for. Using virt-qemu-run as an example, when I run it as root I see that * the domain doesn't show up in the output of 'virsh list' for qemu:///system; * it does, however, show up in the output of 'machinectl', with class=vm and service=libvirt-qemu; * virtlogd is automatically spawned, if not already active, to take care of the domain's log file. The first one is expected, but the other two were a surprise, at least to me. Basically, what I would expect is that qemu:///embed would work in a completely isolated way, only interacting with system-wide components when that's explicitly requested. In other words, I would expect virtlogd not to be spawned, and the domain not to be registered with machinectl; at the same time, if the domain configuration is such that it contains for example <interface type='network'> <source network='default'/> <model type='virtio'/> </interface> then I would expect to see a failure unless a connection to network:///system had been explicitly and pre-emptively opened, and not the current behavior which apparently is to automatically open that connection and spawning virtnetworkd as a result. As a corollary to this, I would expect that two qemu:///embed connections using different roots to be able to define domains with the same name without any problem, but as it stands this is not possible because machinectl will refuse to register the second one. There might be other components that freak out as well, that's just the first one that blocked me. Are my expectations unreasonable? Or should we work towards making sure uses of qemu:///embed don't touch global resources and don't clash with each other? -- Andrea Bolognani / Red Hat / Virtualization

[PATCH 0/5] qemu: Don't log spurious errors on qemuMonitorDelObject
by Peter Krempa 19 Mar '20

[PATCH 0/2] conf: Don't generate clashing machine names for embed driver
by Michal Privoznik 18 Mar '20

18 Mar '20

Inspired by the talk here: https://www.redhat.com/archives/libvir-list/2020-March/msg00232.html Instead of using md5() and the first 6 letters of it, I've decided to go with SHA256 and 8 letters as this offers 16^8 = 4294967296 = 2^32 possibilities, which is the limit of inodes for ext4. If we ever hit a conflict, we can just use 9 letters of the hash.

[PATCH] vmx: make 'fileName' optional for CD-ROMs
by Pino Toscano 18 Mar '20

18 Mar '20

It seems like CD-ROMs may have no 'fileName' property specified in case there is nothing configured as attachment for the drive. Hence, make sure that virVMXParseDisk() do not consider it mandatory anymore, considering it an empty block cdrom device. Sadly virVMXParseDisk() is used also to parse disk and floppies, so make sure that a NULL fileName is handled in cdrom-related paths. https://bugzilla.redhat.com/show_bug.cgi?id=1808610 Signed-off-by: Pino Toscano <ptoscano(a)redhat.com> --- src/vmx/vmx.c | 22 ++++++++++-------- .../vmx2xmldata/vmx2xml-cdrom-ide-empty-2.vmx | 4 ++++ .../vmx2xmldata/vmx2xml-cdrom-ide-empty-2.xml | 23 +++++++++++++++++++ tests/vmx2xmltest.c | 1 + 4 files changed, 40 insertions(+), 10 deletions(-) create mode 100644 tests/vmx2xmldata/vmx2xml-cdrom-ide-empty-2.vmx create mode 100644 tests/vmx2xmldata/vmx2xml-cdrom-ide-empty-2.xml diff --git a/src/vmx/vmx.c b/src/vmx/vmx.c index f0140129a2..58ae966fd4 100644 --- a/src/vmx/vmx.c +++ b/src/vmx/vmx.c @@ -2207,7 +2207,7 @@ virVMXParseDisk(virVMXContext *ctx, virDomainXMLOptionPtr xmlopt, virConfPtr con goto cleanup; /* vmx:fileName -> def:src, def:type */ - if (virVMXGetConfigString(conf, fileName_name, &fileName, false) < 0) + if (virVMXGetConfigString(conf, fileName_name, &fileName, true) < 0) goto cleanup; /* vmx:writeThrough -> def:cachemode */ @@ -2218,7 +2218,7 @@ virVMXParseDisk(virVMXContext *ctx, virDomainXMLOptionPtr xmlopt, virConfPtr con /* Setup virDomainDiskDef */ if (device == VIR_DOMAIN_DISK_DEVICE_DISK) { - if (virStringHasCaseSuffix(fileName, ".vmdk")) { + if (fileName && virStringHasCaseSuffix(fileName, ".vmdk")) { char *tmp; if (deviceType != NULL) { @@ -2254,7 +2254,8 @@ virVMXParseDisk(virVMXContext *ctx, virDomainXMLOptionPtr xmlopt, virConfPtr con if (mode) (*def)->transient = STRCASEEQ(mode, "independent-nonpersistent"); - } else if (virStringHasCaseSuffix(fileName, ".iso") || + } else if (fileName == NULL || + virStringHasCaseSuffix(fileName, ".iso") || STREQ(fileName, "emptyBackingString") || (deviceType && (STRCASEEQ(deviceType, "atapi-cdrom") || @@ -2277,7 +2278,7 @@ virVMXParseDisk(virVMXContext *ctx, virDomainXMLOptionPtr xmlopt, virConfPtr con goto cleanup; } } else if (device == VIR_DOMAIN_DISK_DEVICE_CDROM) { - if (virStringHasCaseSuffix(fileName, ".iso")) { + if (fileName && virStringHasCaseSuffix(fileName, ".iso")) { char *tmp; if (deviceType && STRCASENEQ(deviceType, "cdrom-image")) { @@ -2295,7 +2296,7 @@ virVMXParseDisk(virVMXContext *ctx, virDomainXMLOptionPtr xmlopt, virConfPtr con goto cleanup; } VIR_FREE(tmp); - } else if (virStringHasCaseSuffix(fileName, ".vmdk")) { + } else if (fileName && virStringHasCaseSuffix(fileName, ".vmdk")) { /* * This function was called in order to parse a CDROM device, but * .vmdk files are for harddisk devices only.

[PATCH] qemuDomainVcpuValidateConfig: Properly initialize 'firstcpu' variable
by Peter Krempa 18 Mar '20

18 Mar '20

The loop which checks whether the vcpus are in proper configuration for the requested hot(un)plug skips the first modified vcpu. This means that 'firstvcpu' which is used to print the error message in case the configuration is not suitable would never point to the first modified vcpu. In cases such as: <vcpu placement='auto' current='5'>8</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no'/> <vcpu id='1' enabled='yes' hotpluggable='no'/> <vcpu id='2' enabled='yes' hotpluggable='no'/> <vcpu id='3' enabled='yes' hotpluggable='no'/> <vcpu id='4' enabled='yes' hotpluggable='no'/> <vcpu id='5' enabled='no' hotpluggable='yes'/> <vcpu id='6' enabled='no' hotpluggable='yes'/> <vcpu id='7' enabled='no' hotpluggable='yes'/> </vcpus> # virsh setvcpu --config --disable upstream 1 error: invalid argument: vcpu '-1' can't be modified as it is followed by non-hotpluggable online vcpus After this fix the proper vcpu is reported in the error message: # virsh setvcpu --config --disable upstream 1 error: invalid argument: vcpu '1' can't be modified as it is followed by non-hotpluggable online vcpu https://bugzilla.redhat.com/show_bug.cgi?id=1611061 Signed-off-by: Peter Krempa <pkrempa(a)redhat.com> --- src/qemu/qemu_hotplug.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index 47069be900..a76df64a7b 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -6478,18 +6478,16 @@ qemuDomainVcpuValidateConfig(virDomainDefPtr def, return -1; } + firstvcpu = virBitmapNextSetBit(map, -1); + /* non-hotpluggable vcpus need to stay clustered starting from vcpu 0 */ - for (next = virBitmapNextSetBit(map, -1) + 1; next < maxvcpus; next++) { + for (next = firstvcpu + 1; next < maxvcpus; next++) { if (!(vcpu = virDomainDefGetVcpu(def, next))) continue; /* skip vcpus being modified */ - if (virBitmapIsBitSet(map, next)) { - if (firstvcpu < 0) - firstvcpu = next; - + if (virBitmapIsBitSet(map, next)) continue; - } if (vcpu->online && vcpu->hotpluggable == VIR_TRISTATE_BOOL_NO) { virReportError(VIR_ERR_INVALID_ARG, -- 2.24.1

[PATCH] cpu_map: Add more -noTSX x86 CPU models
by Christian Ehrhardt 18 Mar '20

18 Mar '20

One of the mitigation methods for TAA[1] is to disable TSX support on the host system. Linux added a mechanism to disable TSX globally through the kernel command line, and many Linux distributions now default to tsx=off. This makes existing CPU models that have HLE and RTM enabled not usable anymore. Add new versions of all CPU models that have the HLE and RTM features enabled, that can be used when TSX is disabled in the host system. On systems disabling the features without those types defined in cpu-maps users end up without modern CPU types in the list of usable CPUs to use in the likes of virsh domcapabilities or tools higher in the stack like virt-manager.
