[libvirt] [PATCHv1.5 1/2] cpu:x86: fix specified features will disappear after migrate/restore
by Luyao Huang 23 Jun '15

https://bugzilla.redhat.com/show_bug.cgi?id=1207095 We allow set the feature with the host-passthrough cpu, but won't save them in the migration xml, the features we specified will disappear after migrate/restore.

[libvirt] [PATCHv3] qemu: add a check for slot and base when build dimm address
by Luyao Huang 23 Jun '15

When hot-plug a memory device, we don't check if there is a memory device have the same address with the memory device we want hot-pluged.

[libvirt] [PATCH 0/5 v2] Corrections to SCSI logical unit handling
by Eric Farman 22 Jun '15

22 Jun '15

While working with the hostdev tag and SCSI LUNs, a problem was discovered with the XML schema (see commit message in patch 4). This spawned some further corrections to the handling of the logical unit field throughout libvirt. This series was split from a single patch, from this feedback: http://www.redhat.com/archives/libvir-list/2015-June/msg00489.html Eric Farman (5): Print SCSI logical unit as a positive integer Print SCSI logical unit as unsigned integer Convert SCSI logical unit from int to long long docs: Fix XML schema handling of LUN address in hostdev tag docs: Correct typos in scsi hostdev and address elements docs/formatdomain.html.in | 10 +++++++--- docs/schemas/domaincommon.rng | 14 ++++++++++++-- src/conf/domain_audit.c | 2 +- src/conf/domain_conf.c | 4 ++-- src/conf/domain_conf.h | 2 +- src/qemu/qemu_command.h | 2 +- src/qemu/qemu_hotplug.c | 4 ++-- src/util/virhostdev.c | 6 +++--- src/util/virscsi.c | 16 ++++++++-------- src/util/virscsi.h | 8 ++++---- tests/testutilsqemu.c | 2 +- tools/virsh-domain.c | 6 +++--- 12 files changed, 45 insertions(+), 31 deletions(-) -- 1.9.1

[libvirt] [PATCH v2] parallels: implementation of attach/detach network devices
by Mikhail Feoktistov 22 Jun '15

22 Jun '15

Changes from v1 Remove "cleanup" label and "goto" operator from prlsdkAttachNet() and prlsdkDetachNet() Replace it with "return" operator. Rename netMac variable to expectedMac in prlsdkGetNetIndex() Move prlsdkGetNetIndex() call after PrlVm_BeginEdit call in prlsdkDetachNet() function. Patch comment: In this patch we add VIR_DOMAIN_DEVICE_NET handlers implementation for domainAttachDevice and domainDetachDevice callbacks. As soon as we don't support this operation for hypervisor type domains, we implement this functionality for containers only. In detach procedure we find network device by MAC address. Because PrlVmDevNet_GetMacAddress() returns MAC as a UTF-8 encoded null-terminated string, we use memcmp() to compare it. Also we remove corresponding virtual network by prlsdkDelNetAdapter call. --- src/vz/vz_driver.c | 16 +++++++ src/vz/vz_sdk.c | 123 ++++++++++++++++++++++++++++++++++++++++++++++++++++ src/vz/vz_sdk.h | 4 ++ 3 files changed, 143 insertions(+), 0 deletions(-) diff --git a/src/vz/vz_driver.c b/src/vz/vz_driver.c index cef3c77..d9ddd4f 100644 --- a/src/vz/vz_driver.c +++ b/src/vz/vz_driver.c @@ -1117,6 +1117,14 @@ static int vzDomainAttachDeviceFlags(virDomainPtr dom, const char *xml, goto cleanup; } break; + case VIR_DOMAIN_DEVICE_NET: + ret = prlsdkAttachNet(privdom, privconn, dev->data.net) + if (ret) { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", + _("network attach failed")); + goto cleanup; + } + break; default: virReportError(VIR_ERR_OPERATION_UNSUPPORTED, _("device type '%s' cannot be attached"), @@ -1186,6 +1194,14 @@ static int vzDomainDetachDeviceFlags(virDomainPtr dom, const char *xml, goto cleanup; } break; + case VIR_DOMAIN_DEVICE_NET: + ret = prlsdkDetachNet(privdom, privconn, dev->data.net) + if (ret) { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", + _("network detach failed")); + goto cleanup; + } + break; default: virReportError(VIR_ERR_OPERATION_UNSUPPORTED, _("device type '%s' cannot be detached"), diff --git a/src/vz/vz_sdk.c b/src/vz/vz_sdk.c index 090a3ad..6e6d8c9 100644 --- a/src/vz/vz_sdk.c +++ b/src/vz/vz_sdk.c @@ -2914,6 +2914,129 @@ static void prlsdkDelNet(vzConnPtr privconn, virDomainNetDefPtr net) PrlHandle_Free(vnet); } +int prlsdkAttachNet(virDomainObjPtr dom, parallelsConnPtr privconn, virDomainNetDefPtr net) +{ + int ret = -1; + parallelsDomObjPtr privdom = dom->privateData; + PRL_HANDLE job = PRL_INVALID_HANDLE; + + if (!IS_CT(dom->def)) { + virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", + _("network device cannot be attached")); + return ret; + } + + job = PrlVm_BeginEdit(privdom->sdkdom); + if (PRL_FAILED(waitJob(job))) + return ret; + + ret = prlsdkAddNet(privdom->sdkdom, privconn, net, IS_CT(dom->def)); + if (ret == 0) { + job = PrlVm_CommitEx(privdom->sdkdom, PVCF_DETACH_HDD_BUNDLE); + if (PRL_FAILED(waitJob(job))) { + return -1; + } + } + + return ret; +} + +static int +prlsdkGetNetIndex(PRL_HANDLE sdkdom, virDomainNetDefPtr net) +{ + int idx = -1; + PRL_RESULT pret; + PRL_UINT32 adaptersCount; + PRL_UINT32 i; + PRL_HANDLE adapter = PRL_INVALID_HANDLE; + PRL_UINT32 len; + char adapterMac[PRL_MAC_STRING_BUFNAME]; + char expectedMac[PRL_MAC_STRING_BUFNAME]; + + prlsdkFormatMac(&net->mac, expectedMac); + pret = PrlVmCfg_GetNetAdaptersCount(sdkdom, &adaptersCount); + prlsdkCheckRetGoto(pret, cleanup); + + for (i = 0; i < adaptersCount; ++i) { + + pret = PrlVmCfg_GetNetAdapter(sdkdom, i, &adapter); + prlsdkCheckRetGoto(pret, cleanup); + + len = sizeof(adapterMac); + memset(adapterMac, 0, sizeof(adapterMac)); + pret = PrlVmDevNet_GetMacAddress(adapter, adapterMac, &len); + prlsdkCheckRetGoto(pret, cleanup); + + if (memcmp(adapterMac, expectedMac, PRL_MAC_STRING_BUFNAME)) { + + PrlHandle_Free(adapter); + adapter = PRL_INVALID_HANDLE; + continue; + } + + idx = i; + break; + } + + cleanup: + PrlHandle_Free(adapter); + return idx; +} + +static int prlsdkDelNetAdapter(PRL_HANDLE sdkdom, int idx) +{ + int ret = -1; + PRL_RESULT pret; + PRL_HANDLE sdknet = PRL_INVALID_HANDLE; + + pret = PrlVmCfg_GetNetAdapter(sdkdom, idx, &sdknet); + prlsdkCheckRetGoto(pret, cleanup); + + pret = PrlVmDev_Remove(sdknet); + prlsdkCheckRetGoto(pret, cleanup); + + ret = 0; + + cleanup: + PrlHandle_Free(sdknet); + return ret; +} + +int prlsdkDetachNet(virDomainObjPtr dom, parallelsConnPtr privconn, virDomainNetDefPtr net) +{ + int ret = -1, idx = -1; + parallelsDomObjPtr privdom = dom->privateData; + PRL_HANDLE job = PRL_INVALID_HANDLE; + + if (!IS_CT(dom->def)) { + virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", + _("network device cannot be detached")); + return ret; + } + + job = PrlVm_BeginEdit(privdom->sdkdom); + if (PRL_FAILED(waitJob(job))) + return ret; + + idx = prlsdkGetNetIndex(privdom->sdkdom, net); + if (idx < 0) + return ret; + + ret = prlsdkDelNet(privconn, net); + if (ret != 0) + return ret; + + ret = prlsdkDelNetAdapter(privdom->sdkdom, idx); + if (ret == 0) { + job = PrlVm_CommitEx(privdom->sdkdom, PVCF_DETACH_HDD_BUNDLE); + if (PRL_FAILED(waitJob(job))) { + return -1; + } + } + + return ret; +} + static int prlsdkDelDisk(PRL_HANDLE sdkdom, int idx) { int ret = -1; diff --git a/src/vz/vz_sdk.h b/src/vz/vz_sdk.h index dd4fecf..cde8904 100644 --- a/src/vz/vz_sdk.h +++ b/src/vz/vz_sdk.h @@ -66,3 +66,7 @@ int prlsdkDetachVolume(virDomainObjPtr dom, virDomainDiskDefPtr disk); int prlsdkGetBlockStats(virDomainObjPtr dom, virDomainDiskDefPtr disk, virDomainBlockStatsPtr stats); +int +prlsdkAttachNet(virDomainObjPtr dom, parallelsConnPtr privconn, virDomainNetDefPtr net); +int +prlsdkDetachNet(virDomainObjPtr dom, parallelsConnPtr privconn, virDomainNetDefPtr net); -- 1.7.1

[libvirt] Add hook for network update event
by kay 22 Jun '15

22 Jun '15

Hey guys, This is duplicate from Bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1181539) but I would like to ask you if my patch looks good. "virsh net-update" starts iptables rules reload for NAT network system. This event doesn't start network hooks, so all previous custom iptables rules become unavailable. How reproducible: Add "/etc/libvirt/hooks/network" with: ------------------------------------------- #!/bin/bash echo "`date` $0 $@" >> /var/log/libvirt.log ------------------------------------------- Restart libvirt and run virsh net-update command: virsh net-update default modify ip-dhcp-host --live --config "<host mac='52:54:00:97:eb:95' name='test' ip='192.168.122.253'/>" Actual results: /var/log/libvirt.log log file doesn't contain events from virsh net-update command. Expected results: /var/log/libvirt.log log file should contain event. Additional info: This bug brakes iptables hooks hack for FORWARD chain with NAT network. Patch file is attached. It was tested with libvirt 1.2.15
