Re: [libvirt] [PATCH] Allocate priv->vioserialaddrs unconditionally

When attempting to hotplug a virtio-serial console to a domain that had no virtio-serial controllers (not even those that are added by libvirt when some devices need them) at daemon startup, report a user-friendly error: error: Failed to attach device from console.xml error: internal error: no virtio-serial controllers are available instead of crashing the daemon: Process terminating with default action of signal 11 (SIGSEGV): dumping core Access not within mapped region at address 0x8 at 0x531028F: virDomainVirtioSerialAddrNext (domain_addr.c:916) by 0x531028F: virDomainVirtioSerialAddrAssign (domain_addr.c:1029) by 0x1CBF68: qemuDomainAttachChrDevice (qemu_hotplug.c:1565) by 0x1BCD5E: qemuDomainAttachDeviceLive (qemu_driver.c:7997) by 0x1BCD5E: qemuDomainAttachDeviceFlags (qemu_driver.c:8743) Introduced in v1.2.14-30-g5903378. --- src/qemu/qemu_command.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index d8ce511..11c6823 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1447,9 +1447,6 @@ qemuDomainAssignVirtioSerialAddresses(virDomainDefPtr def, virDomainVirtioSerialAddrSetPtr addrs = NULL; qemuDomainObjPrivatePtr priv = NULL; - if (virDomainControllerFindByType(def, VIR_DOMAIN_CONTROLLER_TYPE_VIRTIO_SERIAL) == -1) - return 0; - if (!(addrs = virDomainVirtioSerialAddrSetCreate())) goto cleanup;
