Hi , For attaching iSCSI disk I have tried like this *iscsi target side :* * 1 created an iqn number* #tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2009-06.com.eucalyptus.cluster1:store1 * 2. added one lun to it* #tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /fs.iscsi.disk * 3.To enable the target to accept any initiators, enter:* #tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL * 4.To view the current configuration, enter:* #tgtadm --lld iscsi --op show --mode target *iscsi initaitor side (where libvirt and xen is running)* * 1. to** scan for the newly created target* * #*iscsiadm -m discovery -t sendtargets -p 192.168.53.14 * 2. created pool file * <pool type="iscsi"> <name>sample3</name> <source> <host name="192.168.53.14"/> <device path="iqn.2009-06.com.eucalyptus.cluster1:store1"/> </source> <target> <path>/dev/disk/by-path</path> </target> </pool> * 3.*#virsh pool-define sample_pool.xml #virsh pool-start sample3 then it created one link like this at */dev/disk/by-path/* *ip-192.168.53.14:3260-iscsi-iqn.2009-06.com.eucalyptus.cluster1:store1-lun-1 -> ../../sdb* 4. I have attached using virsh attach-disk #virsh attach-disk 1 /dev/sdb xvdb It is attached successfully , I console in vm I have checked . But while using with eucalyptus,It is not attching. I'm using eucalyptus 3.4.2 , libvirt 1.2.3 with xen4.3.1 to attach volume to vm . eucalyptus attaching volume is done through iscsi disk , intermediate files are created while attaching volume in xml format as below. *File 1:* <?xml version="1.0" encoding="UTF-8"?> <disk type="block"> <driver cache="none" name="phy"/> <source dev="/dev/disk/by-id/scsi-1IET_00230001"/> <target dev="sdf" bus="scsi"/> <serial>vol-759A3CDB-dev-sdf</serial> </disk> *File 2:* <?xml version="1.0" encoding="UTF-8"?> <volume> <hypervisor type="xen" capability="xen+hw" bitness="64"/> <id>vol-759A3CDB</id> <user>AIDOMCCNSP7YNR7IEZEUX</user> <instancePath>/usr/local/eucalyptus/work/AIDOMCCNSP7YNR7IEZEUX/i-ED153F84</instancePath> <os platform="linux" virtioRoot="false" virtioDisk="false" virtioNetwork="false"/> <backing> <root type="image"/> </backing> <diskPath targetDeviceType="disk" targetDeviceName="sdf" targetDeviceBus="scsi" sourceType="block" serial="vol-759A3CDB-dev-sdf">/dev/disk/by-id/scsi-1IET_00230001</diskPath> </volume> *in libvirtd.log i'm getting* *error : libxlDomainAttachDeviceDiskLive:2567 : unsupported configuration: disk bus 'scsi' cannot be hotplugged.* Can u suggest how to enable or patch to scsi hotplug from libvirt which support for xen.

[libvirt] qemu: managedsave vs. save
by Richard Weinberger 02 May '14

02 May '14

Hi! My KVM hosts share the same filesystem and I'm facing an issue using managedsave. If I save vmX using managedsave on hostA and restore it later using "virsh restore" in hostB the qemu process consumes 100% CPU and makes no progress. On the other hand, if I save vmX using save the restore works fine on hostB. Why can't I restore vms saved by managedsave using restore? Or is this a known issue on libvirt-0.10.X (CentOS 6)? -- Thanks, //richard

[libvirt] [PATCHv2] storageVolCreateXMLFrom: Allow multiple accesses to origvol
by Michal Privoznik 02 May '14

02 May '14

When creating a new volume, it is possible to copy data into it from another already existing volume (referred to as @origvol). Obviously, the read-only access to @origvol is required, which is thread safe (probably not performance-wise though). However, with current code both @newvol and @origvol are marked as building for the time of copying data from the @origvol to @newvol. The rationale behind is to disallow some operations on both @origvol and @newvol, e.g. vol-wipe, vol-delete, vol-download. While it makes sense to not allow such operations on partly copied mirror, but it doesn't make sense to disallow the operations on the source (@origvol).

[libvirt] [PATCH] Restore skipping of setting capacity
by John Ferlan 02 May '14

02 May '14

Commit id 'ac9a0963' refactored out the 'withCapacity' for the virStorageBackendUpdateVolInfo() API. See: http://www.redhat.com/archives/libvir-list/2014-April/msg00043.html This resulted in a difference in how 'virsh vol-info --pool <poolName> <volume>' or 'virsh vol-list vol-list --pool <poolName> --details' outputs the capacity information for a directory pool with a qcow2 sparse file. For example, using the following XML mkdir /home/TestPool cat testpool.xml <pool type='dir'> <name>TestPool</name> <uuid>6bf80895-10b6-75a6-6059-89fdea2aefb7</uuid> <source> </source> <target> <path>/home/TestPool</path> <permissions> <mode>0755</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool> virsh pool-create testpool.xml virsh vol-create-as --pool TestPool temp_vol_1 \ --capacity 1048576 --allocation 1048576 --format qcow2 virsh vol-info --pool TestPool temp_vol_1 Results in listing a Capacity value. Prior to the commit, the value would be '1.0 MiB' (1048576 bytes). However, after the commit the output would be (for example) '192.50 KiB', which for my system was the size of the volume in my file system (eg 'ls -l TestPool/temp_vol_1' results in '197120' bytes or 192.50 KiB). While perhaps technically correct, it's not necessarily what the user expected (certainly virt-test didn't expect it).

v1 was here, but it got nacked for being ugly: https://www.redhat.com/archives/libvir-list/2014-April/msg01132.html so in this version, I improved virstring first, then used the new clean function. This is a build-breaker fix, so it deserves to be in 1.2.4; but it is large enough that it needs a review to go in.

[libvirt] [PATCH] tests: don't fail with newer gnutls
by Martin Kletzander 02 May '14

gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards compatible when it comes to chrooted binaries [1]. Linking commandhelper with gnutls then leaves these two FDs open and commandtest fails thanks to that. This patch does not link commandhelper with libvirt.la, but rather only the utilities making the test pass. Based on suggestion from Daniel [2].

[libvirt] Test failures with newest gnutls
by Martin Kletzander 02 May '14

02 May '14

Hi everyone, after upgrade to gnutls-3.3.0, I discovered (commandtest fails) that any code linked with -lgnutls will have not 3, but 5 open file descriptors upon the entry into main(). I asked on gnutls-help [1] if they know they are leaking file descriptors. The response was, that this is intended with the explanation being that these FDs (pointing to /dev/urandom) are kept open for backward compatibility with programs that may chroot into environment without /dev/urandom as the previous version didn't require to have access to /dev/urandom when calling gnutls code. Does that seem like our bug that we're relying on fixed number of open file descriptors? Or that we're linking to gnutls when we don't need it in commandhelper? Or should this be fixed somewhere else? Have a nice day, Martin [1] http://lists.gnutls.org/pipermail/gnutls-help/2014-April/003415.html
