[libvirt] [PATCH] storage: Activate/deactivate logical volumes only on local node
by Osier Yang 12 Dec '11

12 Dec '11

From: Rommer <rommer(a)active.by> Current "-ay | -an" has problems on pool starting/refreshing if the volumes are clustered. Rommer has posted a patch to list 2 months ago. https://www.redhat.com/archives/libvir-list/2011-October/msg01116.html But IMO we shouldn't skip the inactived vols. So this is a squashed patch by Rommer.

[libvirt] [PATCH v2 0/4] Interface pools and passthrough mode
by Shradha Shah 12 Dec '11

12 Dec '11

Interface Pools and Passthrough mode: Current Method: The passthrough mode uses a macvtap direct connection to connect each guest to the network. The physical interface to be used is picked from among those listed in <interface> sub elements of the <forward> element. The current specification for <forward> extends to allow 0 or more <interface> sub-elements: Example: <forward mode='passthrough' dev='eth10'/> <interface dev='eth10'/> <interface dev='eth12'/> <interface dev='eth18'/> <interface dev='eth20'/> </forward> However with an ethernet card with 64 VF's or more, the above method gets tedious on the system. On the other hand, just parameterizing a string (eth%d) is inadequate, eg, when there are multiple non-contiguous ranges. Proposed Method: The 4 patches provided: i) Introduce a new element 'pf' to implicitly create an interface pool of all the Virtual Functions attached to the specified Physical Function. ii) Modify the networkAllocateActualDevice, networkNotifyActualDevice and networkReleaseActualDevice API to use the above mentioned interface pool in the passthrough mode. Hence Libvirt will now support both the methods mentioned below: * Explicit interface list. App inputs: <forward mode='passthrough'> <interface dev='eth10'/> <interface dev='eth11'/> <interface dev='eth12'/> <interface dev='eth13'/> </forward> libvirt does not change XML * Automatically interface list from PF. App inputs: <forward mode='passthrough'> <pf dev='eth0'/> </forward> libvirt expands XML to be <forward mode='passthrough'> <pf dev='eth0'/> <interface dev='eth10'/> <interface dev='eth11'/> <interface dev='eth12'/> <interface dev='eth13'/> </forward> In the above case we need to differentiate between the implicit and explicit interface pool, which can be done by comparing the dumpxml from active and inactive domains. This will need the addition of the flag VIR_NETWORK_XML_INACTIVE to virNetworkGetXMLDesc() as mentioned in a previous suggestion. I will post this as a separate patch series. Shradha Shah (4): Added function pciSysfsFile to enable access to the PCI SYSFS files. Added Function virNetDevGetVirtualFunctions Adding the element pf to network xml. Functionality to implicitly get interface pool from SR-IOV PF. docs/schemas/network.rng | 7 +++ src/conf/network_conf.c | 69 ++++++++++++++++++++++++++++++-- src/conf/network_conf.h | 3 + src/network/bridge_driver.c | 93 +++++++++++++++++++++++++++++++++--------- src/util/pci.c | 39 ++++++++++++++++++ src/util/pci.h | 7 +++ src/util/virnetdev.c | 83 ++++++++++++++++++++++++++++++++++++++ src/util/virnetdev.h | 6 +++ 8 files changed, 283 insertions(+), 24 deletions(-) -- 1.7.4.4

[libvirt] [PATCH] security: don't try to label network disks
by Josh Durgin 12 Dec '11

12 Dec '11

Network disks don't have paths to be resolved or files to be checked for ownership. ee3efc41e6233e625aa03003bf3127319ccd546f checked this for some image label functions, but was partially reverted in a refactor. This finishes adding the check to each security driver's set and restore label methods for images.

[libvirt] Virtio Balloon Dynamic behaviour ??
by Pankaj Rawat 12 Dec '11

12 Dec '11

Hi all, I want to be clear in details regarding Virtio balloon Driver in RHEL 6.1 KVM hypervisor In documentations it is written that Virtio balloon driver allow the guest to expand its memory dynamically . Now I want to know the meaning of dynamically ... Whether it means 1) We can change the memory of guest using libvirt API only i.e by using virsh setmem command at runtime (VERIFIED) 2) Or the guest itself can check that it is running out of memory so it request host for some memory and when the host respond by giving back memory it expands its memory size. Which is automation The 1st option is working fine Now can anyone tell me that memory expantion can be done dynamically(point 2) also DISCLAIMER: ----------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
