[libvirt] [PATCH 1/3] qemu: Re-reserve all PCI addresses on libvirtd restart

When reconnecting to existing VMs, we re-reserved only those PCI addresses which were explicitly mentioned in domain XML. Since some addresses are always reserved (e.g., 0:0:0 and 0:0:1), we need to handle those too. Also all this should only be done if device flag is supported by qemu. --- src/qemu/qemu_driver.c | 8 +++++--- 1 files changed, 5 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index e718816..2ca3940 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1455,11 +1455,13 @@ qemuReconnectDomain(void *payload, const char *name ATTRIBUTE_UNUSED, void *opaq if (qemudExtractVersionInfo(obj->def->emulator, NULL, &qemuCmdFlags) >= 0 && - (qemuCmdFlags & QEMUD_CMD_FLAG_DEVICE)) + (qemuCmdFlags & QEMUD_CMD_FLAG_DEVICE)) { priv->persistentAddrs = 1; - if (!(priv->pciaddrs = qemuDomainPCIAddressSetCreate(obj->def))) - goto error; + if (!(priv->pciaddrs = qemuDomainPCIAddressSetCreate(obj->def)) || + qemuAssignDevicePCISlots(obj->def, priv->pciaddrs) < 0) + goto error; + } if (driver->securityDriver && driver->securityDriver->domainReserveSecurityLabel && -- 1.7.2
