[libvirt] [PATCH] qemu: Add a capability flag for -no-acpi
by Michael Ellerman 21 Dec '11

21 Dec '11

Currently non-x86 guests must have <acpi/> defined in <features> to prevent libvirt from running qemu with -no-acpi. Although it works, it is a hack. Instead add a capability flag which indicates whether qemu understands the -no-acpi option. Use it to control whether libvirt emits -no-acpi. Current versions of qemu always display -no-acpi in their help output, so this patch has no effect. However the development version of qemu has been modified such that -no-acpi is only displayed when it is actually supported.

[libvirt] [PATCH] virsh: Fix a regression of detaching device
by Osier Yang 20 Dec '11

20 Dec '11

Since for node <address>, the values for attrs "domain", "bus", "slot", "function" are all converted to heximal when parsing the XML. However commit ea7182c29 tries to examine if the device represented by the XML from user exists in the domain XML earlier before the XML parsing, and thus if the user use different base to represent the device address, e.g. <address type='pci' domain='0' bus='0' slot='7'/> vshCompleteXMLFromDomain won't find the device, and quit with error "no such device" even if the device does exist. --- tools/virsh.c | 41 +++++++++++++++++++++++++++++++++++------ 1 files changed, 35 insertions(+), 6 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index 3654589..5c78995 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -12107,12 +12107,14 @@ vshNodeIsSuperset(xmlNodePtr n1, xmlNodePtr n2) { xmlNodePtr child1, child2; xmlAttrPtr attr; - char *prop1, *prop2; + char *prop1 = NULL; + char *prop2 = NULL; bool found; bool visited; bool ret = false; long n1_child_size, n2_child_size, n1_iter; - virBitmapPtr bitmap; + virBitmapPtr bitmap = NULL; + unsigned int prop1_ui, prop2_ui; if (!n1 && !n2) return true; @@ -12129,13 +12131,36 @@ vshNodeIsSuperset(xmlNodePtr n1, xmlNodePtr n2) if (attr->type == XML_ATTRIBUTE_NODE) { prop1 = virXMLPropString(n1, (const char *) attr->name); prop2 = virXMLPropString(n2, (const char *) attr->name); - if (STRNEQ_NULLABLE(prop1, prop2)) { - xmlFree(prop1); - xmlFree(prop2); - return false; + + if (STREQ((const char *)n2->name, "address") && + prop1 && prop2 && + (STREQ((const char *)attr->name, "domain") || + STREQ((const char *)attr->name, "bus") || + STREQ((const char *)attr->name, "slot") || + STREQ((const char *)attr->name, "function"))) { + if (virStrToLong_ui(prop1, NULL, 0, &prop1_ui) < 0) { + vshError(NULL, _("can't parse value for %s"), attr->name); + goto cleanup; + } + + if (virStrToLong_ui(prop2, NULL, 0, &prop2_ui) < 0) { + vshError(NULL, _("can't parse value for %s"), attr->name); + goto cleanup; + } + + if (prop1_ui != prop2_ui) { + goto cleanup; + } + } else { + if (STRNEQ_NULLABLE(prop1, prop2)) { + goto cleanup; + } } + xmlFree(prop1); + prop1 = NULL; xmlFree(prop2); + prop2 = NULL; } attr = attr->next; } @@ -12207,6 +12232,10 @@ vshNodeIsSuperset(xmlNodePtr n1, xmlNodePtr n2) ret = true; cleanup: + if (prop1) + xmlFree(prop1); + if (prop2) + xmlFree(prop2); virBitmapFree(bitmap); return ret; } -- 1.7.7.3

[libvirt] polkit-auth question
by Jim Fehlig 20 Dec '11

20 Dec '11

While debugging a PolicyKit issue I noticed that libvirt would proceed with authentication even though polkit-auth failed: testusr@xen134:~> virsh list --all Attempting to obtain authorization for org.libvirt.unix.manage. polkit-grant-helper: given auth type (8 -> yes) is bogus Failed to obtain authorization for org.libvirt.unix.manage. Id Name State ---------------------------------- 0 Domain-0 running - sles11sp1-pv shut off Hmm, authorization failed but domains listed anyway. testusr@xen134:~> virsh start sles11sp1-pv Attempting to obtain authorization for org.libvirt.unix.manage. polkit-grant-helper: given auth type (8 -> yes) is bogus Failed to obtain authorization for org.libvirt.unix.manage. Domain sles11sp1-pv started Ok, authorization failed but testusr was able to start the domain! Checking virConnectAuthGainPolkit() in src/libvirt.c cmd = virCommandNewArgList(POLKIT_AUTH, "--obtain", privilege, NULL); if (virCommandRun(cmd, &status) < 0 || status > 1) goto cleanup; Why the check for status > 1? I looked at polkit-auth source in PolicyKit 0.9 and AFAICT it sets its default return code to 1, only changing it to 0 in success code paths. Unfortunately, the polkit-auth docs make no mention of return codes. Thanks, Jim
