[libvirt] CPU type/flags when converting a physical machine to run on libvirt
by Richard W.M. Jones
I'm in the process of rewriting virt-p2v which is our program for
converting physical machines to become virtual machines, running on
top of libvirt + KVM.
The physical machine has certain characteristics -- eg:
- number of physical cores
- amount of RAM
- CPU type (eg. AMD Opteron, Intel Core i7)
- CPU flags (eg. ACPI, SSE4)
which it might make sense to reflect in the libvirt XML of the virtual
machine we create.
The old version of virt-p2v is pretty simplistic about this. It
generates *only* an i386 or x86-64 VM, and the only flags it considers
are 'apic', 'acpi', 'pae' and 'lm' [the latter to distinguish between
32 and 64 bit x86].
What should the new version do?
Particular questions:
- Should we try to reflect the CPU type of the physical machine in
the virtual machine? eg. If it's an Opteron, we generate an
Opteron target machine. (I believe the answer is *no*, because
this is not live migration, and most guests can boot on any
compatible CPU).
- How can I ask libvirt to give me the best possible CPU, and not
some baseline? Normally I use host-model, but I think that
prevents migration.
- What CPU flags should be reflected in the target libvirt XML?
- Is it worth modelling CPU thread layout? (I suspect this will be a
lot of work with the potential to break things rather than provide
any measurable benefits.)
- Is there anything else I haven't thought about?
However the overriding rule is:
- We *must not* end up with a target virtual machine which doesn't work!
Rich.

[libvirt] Reg : failing to attach iscsi disk from virsh to running VM on xen
by Prapulla Kumar
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.
Can u say the meaning of PATCH 11/12 what is 11/12 means.
eg ; [libvirt] [PATCH 11/12] Properly support SCSI drive hotplug

[libvirt] qemu: managedsave vs. save
by Richard Weinberger
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)?

[libvirt] [PATCHv2] storageVolCreateXMLFrom: Allow multiple accesses to origvol
by Michal Privoznik
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
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).
This patch restores the code to not update the target capacity for this path

[libvirt] [PATCHv2 0/3] fix virstoragetest failure on 32-bit
by Eric Blake
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.
Eric Blake (3):
util: fix uint parsing on 64-bit platforms
util: new stricter unsigned int parsing
storage: reject negative indices
