[libvirt] [PATCH] qemu: rename: Forbid renaming domains with managed save image
by Peter Krempa 07 Mar '16

07 Mar '16

The code does not handle renaming of the save state file. In addition to that the resuming code would need to be tweaked to handle the name change since the XML is extracted from the save image. The easies option is to make the rename API even less useful by forbiding this. --- src/qemu/qemu_driver.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 102fade..4020364 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -19994,6 +19994,12 @@ static int qemuDomainRename(virDomainPtr dom, goto endjob; } + if (vm->hasManagedSave) { + virReportError(VIR_ERR_OPERATION_INVALID, "%s", + _("domain with a managed saved state can't be renamed")); + goto endjob; + } + if (virDomainObjGetState(vm, NULL) != VIR_DOMAIN_SHUTOFF) { virReportError(VIR_ERR_OPERATION_INVALID, "%s", _("domain has to be shutoff before renaming")); -- 2.6.2

[libvirt] [PATCH] Use correct pci addresses during interface-detach[v2]
by Nitesh Konkar 07 Mar '16

07 Mar '16

The virsh attach virsh detach interface command fails when both live and config are set and when the interface gets attached to different pci slots on live and config xml respectively. When we attach an interface with both --live and --config, the first time they get the same PCI slots, but the second time onwards it differs and hence the virsh detach-interface --live --config command fails. This patch makes sure that when both --live --config are set , qemuDomainDetachDeviceFlags is called twice, once with config xml and once with live xml. Steps to see the issue: virsh attach-interface --domain DomainName --type network --source default --mac 52:54:00:4b:76:5f --live --config virsh detach-interface --domain DomainName --type network --mac 52:54:00:4b:76:5f --live --config virsh attach-interface --domain DomainName --type network --source default --mac 52:54:00:4b:76:5f --live --config virsh detach-interface --domain DomainName --type network --mac 52:54:00:4b:76:5f --live --config Signed-off-by:nitkon12@linux.vnet.ibm.com --- tools/virsh-domain.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/tools/virsh-domain.c b/tools/virsh-domain.c index 62acecb..43c8436 100644 --- a/tools/virsh-domain.c +++ b/tools/virsh-domain.c @@ -10815,7 +10815,7 @@ cmdDetachInterface(vshControl *ctl, const vshCmd *cmd) char buf[64]; int diff_mac; size_t i; - int ret; + int ret, flag_live_config_both = 0; bool functionReturn = false; unsigned int flags = VIR_DOMAIN_AFFECT_CURRENT; bool current = vshCommandOptBool(cmd, "current"); @@ -10830,7 +10830,7 @@ cmdDetachInterface(vshControl *ctl, const vshCmd *cmd) if (config || persistent) flags |= VIR_DOMAIN_AFFECT_CONFIG; - if (live) + if (!(config || persistent) && live) // Only Live flags |= VIR_DOMAIN_AFFECT_LIVE; if (!(dom = virshCommandOptDomain(ctl, cmd, NULL))) @@ -10851,6 +10851,8 @@ cmdDetachInterface(vshControl *ctl, const vshCmd *cmd) else doc = virDomainGetXMLDesc(dom, 0); + forlivexml: + if (!doc) goto cleanup; @@ -10921,6 +10923,14 @@ cmdDetachInterface(vshControl *ctl, const vshCmd *cmd) if (ret != 0) { vshError(ctl, "%s", _("Failed to detach interface")); } else { + if ((config || persistent) && live && flag_live_config_both == 0) {//executed only when live config both in cmd. + doc = virDomainGetXMLDesc(dom, 0); + flag_live_config_both=1; //Need to execute this code only once + flags |= VIR_DOMAIN_AFFECT_LIVE; //set live flag + flags &= (~VIR_DOMAIN_AFFECT_CONFIG ); // need to unset config flag as config xml detach is already done. + mac=NULL; + goto forlivexml; + } vshPrint(ctl, "%s", _("Interface detached successfully\n")); functionReturn = true; } -- 1.8.3.1
