Re: [libvirt] [RHEL6 PATCH] Correct cpuid flags and "model" fields, V2
by john cooper 04 Aug '10

04 Aug '10

A question arose in today's kvm meeting concerning any impact to libvirt from this change. I've discussed it with Cole and it seems to be a non-issue. But just to err on the side of caution, here's a summary: The current cpu model definition of "qemu64" upstream is problematic from kvm's perspective such that we need to modify it slightly (BZ justifications listed below). Doing so we've left the qemu64 definition as-is, but added "cpu64-rhel6" and "cpu64-rhel5" models which are now selected by default via "-M <machine>", for "RHEL 6.0.0 PC" and "RHEL 5.x.y PC" respectively. So the only issue would be libvirt invoking qemu with neither a "-cpu" nor "-M" argument (which defaults to qemu64) or explicitly requesting "-cpu qemu64". >From my discussion with Cole it appears the use cases where this may happen fall outside of routine/expected usage and would need to be explicitly requested by the user. However I wanted to call this out here in the event we're overlooking something.

[libvirt] [PATCH] qemu: Fix PCI address allocation
by Jiri Denemark 04 Aug '10

04 Aug '10

When attaching a PCI device which doesn't explicitly set its PCI address, libvirt allocates the address automatically. The problem is that when checking which PCI address is unused, we only check for those with slot number higher than the highest slot number ever used. Thus attaching/detaching such device several times in a row (31 is the theoretical limit, less then 30 tries are enough in practise) makes any further device attachment fail. Furthermore, attaching a device with predefined PCI address to 0:0:31 immediately forbids attachment of any PCI device without explicit address. This patch changes the logic so that we always check all PCI addresses before we say there is no PCI address available. --- src/qemu/qemu_conf.c | 14 ++++---------- 1 files changed, 4 insertions(+), 10 deletions(-) diff --git a/src/qemu/qemu_conf.c b/src/qemu/qemu_conf.c index 57bc02f..eaebcc1 100644 --- a/src/qemu/qemu_conf.c +++ b/src/qemu/qemu_conf.c @@ -2055,8 +2055,6 @@ qemuAssignDeviceAliases(virDomainDefPtr def, unsigned long long qemuCmdFlags) #define QEMU_PCI_ADDRESS_LAST_SLOT 31 struct _qemuDomainPCIAddressSet { virHashTablePtr used; - int nextslot; - /* XXX add domain, bus later when QEMU allows > 1 */ }; @@ -2148,9 +2146,6 @@ int qemuDomainPCIAddressReserveAddr(qemuDomainPCIAddressSetPtr addrs, return -1; } - if (dev->addr.pci.slot > addrs->nextslot) - addrs->nextslot = dev->addr.pci.slot + 1; - return 0; } @@ -2217,7 +2212,7 @@ int qemuDomainPCIAddressSetNextAddr(qemuDomainPCIAddressSetPtr addrs, { int i; - for (i = addrs->nextslot ; i <= QEMU_PCI_ADDRESS_LAST_SLOT ; i++) { + for (i = 0 ; i <= QEMU_PCI_ADDRESS_LAST_SLOT ; i++) { virDomainDeviceInfo maybe; char *addr; @@ -2228,13 +2223,14 @@ int qemuDomainPCIAddressSetNextAddr(qemuDomainPCIAddressSetPtr addrs, addr = qemuPCIAddressAsString(&maybe); - VIR_DEBUG("Allocating PCI addr %s", addr); - if (virHashLookup(addrs->used, addr)) { + VIR_DEBUG("PCI addr %s already in use", addr); VIR_FREE(addr); continue; } + VIR_DEBUG("Allocating PCI addr %s", addr); + if (virHashAddEntry(addrs->used, addr, addr) < 0) { VIR_FREE(addr); return -1; @@ -2245,8 +2241,6 @@ int qemuDomainPCIAddressSetNextAddr(qemuDomainPCIAddressSetPtr addrs, dev->addr.pci.bus = 0; dev->addr.pci.slot = i; - addrs->nextslot = i + 1; - return 0; } -- 1.7.2

Re: [libvirt] [virt-tools-list] Add a manually configured XEN
by Michal Novotny 03 Aug '10

03 Aug '10

Hi, I can see the point Bernhard. It seems that libvirt is not aware of this guest. Well, if virsh (part of libvirt) is seeing the guest only then the guest is running then you need to create a configuration for that in the libvirt itself. I know there's something like: virsh domxml-from-native <format> <config> but I never used it so I don't know about the config and format and how does it work. Please try asking the libvirt guys on the libvirt list (I put this list in CC now).

[libvirt] [PATCH] [RFC] ISCSI transport protocol support in libvirt
by Aurelien ROUGEMONT 03 Aug '10

03 Aug '10

Hi everyone, This my first post on this list Context : Some days ago I have decided to use infiniband for ISCSI streams. Infiniband adds a new wonderful transport protocol : ISER. This protocols is added to the well known the default TCP. (NB: ISER = ISCSI + RDMA). I could not see any ISCSI transport protocol modification support in libivirt (the default protocol tcp is even hardcoded in the regex) What i have done : - did the shell testing for the iscsiadm - the attached patch that corrects 2 typos in the original code and switches completely the iscsi transport protocol from tcp to iser (which is not ideal at all) What should be done (imho): - add iscsi transport protocol support (using my patch as a basis) - add a new XML property/whatever_fits_the_projects_policy to the storagepool object that allows user to pick the iscsi transport protocol (default is tcp) I was thinking of having something like : <pool type="iscsi"> <name>volumename</name> <source> <host name="1.2.3.4"/> <device path="IQNOFTARGET"/> <transport protocol="iser"/> </source> <target> <path>/dev/disk/by-path</path> </target> </pool> Any comment on this ? Any help on the XML part ? Best regards, Aurélien NB: the current iscsi transport protocols available are : tcp(default), iser, qla4xxx, bnx2, and icxgb3i. PS: i'm still doing extensive testing of my patch !DSPAM:4c46f49d90977882820711!

[libvirt] [PATCH] esx: Restrict vpx:// to handle a single host in a vCenter
by Matthias Bolte 02 Aug '10

02 Aug '10

Now a vpx:// connection has an explicitly specified host. This allows to enabled several functions for a vpx:// connection again, like host UUID, hostname, general node info, max vCPU count, free memory, migration and defining new domains. Lookup datacenter, compute resource, resource pool and host system once and cache them. This simplifies the rest of the code and reduces overall HTTP(S) traffic a bit. esx:// and vpx:// can be mixed freely for a migration. Ensure that migration source and destination refer to the same vCenter. Also directly encode the resource pool and host system object IDs into the migration URI in the prepare function. Then directly build managed object references in the perform function instead of re-looking up already known information. --- docs/drvesx.html.in | 33 +++- src/esx/esx_driver.c | 360 ++++++++++---------------- src/esx/esx_storage_driver.c | 24 +-- src/esx/esx_vi.c | 588 ++++++++++++++++++++++++++---------------- src/esx/esx_vi.h | 26 ++- src/esx/esx_vmx.c | 4 + 6 files changed, 561 insertions(+), 474 deletions(-) diff --git a/docs/drvesx.html.in b/docs/drvesx.html.in index 4ae7a51..dfc91bb 100644 --- a/docs/drvesx.html.in +++ b/docs/drvesx.html.in @@ -28,7 +28,7 @@ Some example remote connection URIs for the driver are: </p> <pre> -vpx://example-vcenter.com (VPX over HTTPS) +vpx://example-vcenter.com/dc1/srv1 (VPX over HTTPS, select ESX server 'srv1' in datacenter 'dc1') esx://example-esx.com (ESX over HTTPS) gsx://example-gsx.com (GSX over HTTPS) esx://example-esx.com/?transport=http (ESX over HTTP) @@ -48,7 +48,7 @@ esx://example-esx.com/?no_verify=1 (ESX over HTTPS, but doesn't verify the s URIs have this general form (<code>[...]</code> marks an optional part). </p> <pre> -type://[username@]hostname[:port]/[?extraparameters] +type://[username@]hostname[:port]/[datacenter[/cluster]/server][?extraparameters] </pre> <p> The <code>type://</code> is either <code>esx://</code> or @@ -58,6 +58,20 @@ type://[username@]hostname[:port]/[?extraparameters] is 443, for <code>gsx://</code> it is 8333.
