Some qemu arch/machine types have built in platform devices that are always implicitly available. For platform serial devices, the current code assumes that only old style -serial config can be used for these devices.
Apparently though since -chardev was introduced, we can use -chardev in these cases, like this: -chardev pty,id=foo -serial chardev:foo Since -chardev enables all sorts of modern features, use this method for platform devices.

I'd appreciate if other folks can test it as well to make sure extra features like <log> work as expected src/qemu/qemu_command.c | 125 ++------------------- src/qemu/qemu_process.c | 9 +- .../qemuxml2argv-aarch64-kvm-32-on-64.args | 3 +- ...l2argv-aarch64-virt-2.6-virtio-pci-default.args | 3 +- .../qemuxml2argv-aarch64-virt-virtio.args | 3 +- .../qemuxml2argv-aarch64-virtio-pci-default.args | 3 +- .../qemuxml2argv-arm-vexpressa9-basic.args | 3 +- .../qemuxml2argv-arm-vexpressa9-virtio.args | 3 +- .../qemuxml2argv-arm-virt-virtio.args | 3 +- tests/qemuxml2argvdata/qemuxml2argv-ppc-dtb.args | 3 +- .../qemuxml2argv-ppce500-serial.args | 3 +- 11 files changed, 32 insertions(+), 129 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 056e62129..3e82ca086 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -5514,106 +5514,6 @@ qemuBuildHostdevCommandLine(virCommandPtr cmd, return 0; } -static char * -qemuBuildChrArgStr(const virDomainChrSourceDef *dev, - const char *prefix) -{ - virBuffer buf = VIR_BUFFER_INITIALIZER; - - if (dev->logfile) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("logfile not supported in this QEMU binary")); - goto error; - } - - if (prefix) - virBufferAdd(&buf, prefix, strlen(prefix)); - - switch ((virDomainChrType)dev->type) { - case VIR_DOMAIN_CHR_TYPE_NULL: - virBufferAddLit(&buf, "null"); - break; - - case VIR_DOMAIN_CHR_TYPE_VC: - virBufferAddLit(&buf, "vc"); - break; - - case VIR_DOMAIN_CHR_TYPE_PTY: - virBufferAddLit(&buf, "pty"); - break; - - case VIR_DOMAIN_CHR_TYPE_DEV: - virBufferStrcat(&buf, dev->data.file.path, NULL); - break; - - case VIR_DOMAIN_CHR_TYPE_FILE: - virBufferAsprintf(&buf, "file:%s", dev->data.file.path); - break; - - case VIR_DOMAIN_CHR_TYPE_PIPE: - virBufferAsprintf(&buf, "pipe:%s", dev->data.file.path); - break; - - case VIR_DOMAIN_CHR_TYPE_STDIO: - virBufferAddLit(&buf, "stdio"); - break; - - case VIR_DOMAIN_CHR_TYPE_UDP: { - const char *connectHost = dev->data.udp.connectHost; - const char *bindHost = dev->data.udp.bindHost; - const char *bindService = dev->data.udp.bindService; - - if (connectHost == NULL) - connectHost = ""; - if (bindHost == NULL) - bindHost = ""; - if (bindService == NULL) - bindService = "0"; - - virBufferAsprintf(&buf, "udp:%s:%s@%s:%s", - connectHost, - dev->data.udp.connectService, - bindHost, - bindService); - break; - } - case VIR_DOMAIN_CHR_TYPE_TCP: - if (dev->data.tcp.protocol == VIR_DOMAIN_CHR_TCP_PROTOCOL_TELNET) { - virBufferAsprintf(&buf, "telnet:%s:%s%s", - dev->data.tcp.host, - dev->data.tcp.service, - dev->data.tcp.listen ?
