[libvirt] [PATCH 0/3] esx: Storage volume up- and download
by Matthias Bolte 08 Jul '12

08 Jul '12

I started the download part and the stream driver quite a while ago but stopped and put it aside as I realized that the storage volume API up- and download functions assume one file per volume. This is a problem with ESX as a VMDK can consist of two files. To solve this now I added two new flags: METADATA and CONTENT. With this flags the user can specify which part of such a volume to transfer. See patch 3/3 for more details. Matthias

Re: [libvirt] [fedora-virt] qemu 1.1.0 in Rawhide, and planned backport to F17 (was: Re: Upgrading qemu to 1.1 in rawhide)
by Richard W.M. Jones 06 Jul '12

[On the topic of qemu 1.1.0 in Fedora 17] I'm seeing some very peculiar problems with virt-install that might be due to libvirt. Is libvirt in F17 too old for qemu 1.1.0? ------- (1) Just installing qemu-system-x86 isn't enough for libvirt to recognize any hypervisors: ERROR Host does not support any virtualization options virsh capabilities doesn't show any <guest> section at all. Of course qemu-kvm *is* installed and working. Solution: install the qemu meta-package. Unfortunately that means I have to have qemu-system-{cris,sh4,arm,mips} which I didn't want. (2) If I use virt-install --cpu=host, I get: ERROR unsupported configuration: CPU specification not supported by hypervisor Solution was to not use this option. (3) Now virt-install says: ERROR internal error process exited while connecting to monitor: char device redirected to /dev/pts/19 Error: Cirrus VGA not available Solution was to use --graphics=spice. (4) Now virt-install says: ERROR internal error process exited while connecting to monitor: char device redirected to /dev/pts/19 do_spice_init: starting 0.10.1 spice_server_add_interface: SPICE_INTERFACE_MIGRATION spice_server_add_interface: SPICE_INTERFACE_KEYBOARD spice_server_add_interface: SPICE_INTERFACE_MOUSE Kernel image must be specified The error here is "Kernel image must be specified". By this point it was getting very strange, so I decided to look at the libvirt log files for the qemu command line ...

[libvirt] [PATCH] [libvirt-java] Fix Array IndexOutOfBoundsException for unknown error codes
by Claudio Bley 06 Jul '12

06 Jul '12

Hi. I'm using libvirt-java 0.4.7 and libvirt 0.9.8. When libvirt returns an error code which is not mapped in enum ErrorNumber, an IndexOutOfBoundsException is thrown. I realize that the freshly released libvirt-java 0.4.8 supports all error codes up to libvirt 0.9.12. But that doesn't fix the problem. Would it be feasible to add a special UNKNOWN enum value? --- diff --git a/src/main/java/org/libvirt/Error.java b/src/main/java/org/libvirt/Error.java index 0946030..72bc698 100644 --- a/src/main/java/org/libvirt/Error.java +++ b/src/main/java/org/libvirt/Error.java @@ -151,9 +151,12 @@ public class Error implements Serializable { } public Error(virError vError) { - code = ErrorNumber.values()[vError.code]; - domain = ErrorDomain.values()[vError.domain]; - level = ErrorLevel.values()[vError.level]; + if (ErrorNumber.values().length > vError.code) + code = ErrorNumber.values()[vError.code]; + if (ErrorDomain.values().length > vError.domain) + domain = ErrorDomain.values()[vError.domain]; + if (ErrorLevel.values().length > vError.level) + level = ErrorLevel.values()[vError.level]; message = vError.message; str1 = vError.str1; str2 = vError.str2; --- Best regards, Claudio. -- AV-Test GmbH, Henricistraße 20, 04155 Leipzig, Germany Phone: +49 341 265 310 19 Web:<http://www.av-test.org> Eingetragen am / Registered at: Amtsgericht Stendal (HRB 114076) Geschaeftsfuehrer (CEO): Andreas Marx, Guido Habicht, Maik Morgenstern -- AV-Test GmbH, Henricistraße 20, 04155 Leipzig, Germany Phone: +49 341 265 310 19 Web:<http://www.av-test.org> Eingetragen am / Registered at: Amtsgericht Stendal (HRB 114076) Geschaeftsfuehrer (CEO): Andreas Marx, Guido Habicht, Maik Morgenstern

[libvirt] [PATCH 00/12] Fine grained access control for libvirt APIs
by Daniel P. Berrange 06 Jul '12

06 Jul '12

This is a repost of https://www.redhat.com/archives/libvir-list/2012-January/msg00907.html which got no comments last time out. This series of patch is the minimal required to get a working proof of concept implementation of fine grained access control in libvirt. This demonstrates - Obtaining a client identity from a socket - Ensuring RPC calls are executed with the correct identity sset - A policykit access driver that checks based on access vector alone - A SELinux access driver that checks based on access vector + object - A set of hooks in the QEMU driver to protect virDomainObjPtr access Things that are not done - APIs for changing the real/effective identity post-connect - A simple RBAC access driver for doing (Access vector, object) checks - SELinux policy for the SELinux driver - Access control hooks on all other QEMU driver methods - Access control hooks in LXC, UML, other libvirtd side drivers - Access control hooks in storage, network, interface, etc drivers - Document WTF todo to propagate SELinux contexts across TCP sockets using IPSec. Any hints welcome... - Lots more I can't think of right now I should note that the policykit driver is mostly useless because it is unable to let you do checks on anything other than permission name and UNIX process ID at this time. So what I've implemented with the polkit driver is really little more than a slightly more fine grained version of the VIR_CONNECT_RO flag. In theory it is supposed to be extendable to allow other types of identity information besides the process ID, and to include some kind of object identiers in the permission check, but no one seems to be attacking this. So I expect the simple RBAC driver to be the most used one in the common case usage of libvirt, and of course the SELinux driver.

[libvirt] [PATCH libvirt-java 1/2] Return a byte[] array with secretGetValue
by Wido den Hollander 05 Jul '12

05 Jul '12

We break the API with this, but Java does not support multiple method signatures with different return types. The old method returned a String, but since a secret can be binary data this type is not suited. Users who now that their secret is in fact a String, can use cast with: Secret secret = conn.secretLookupByUUIDString("uuuuuuuid"); String value = new String(secret.getValue()); Signed-off-by: Wido den Hollander <wido(a)widodh.nl> --- src/main/java/org/libvirt/Secret.java | 13 ++++++++++--- src/main/java/org/libvirt/jna/Libvirt.java | 2 +- 2 files changed, 11 insertions(+), 4 deletions(-) diff --git a/src/main/java/org/libvirt/Secret.java b/src/main/java/org/libvirt/Secret.java index 48f7895..39d9122 100644 --- a/src/main/java/org/libvirt/Secret.java +++ b/src/main/java/org/libvirt/Secret.java @@ -5,6 +5,9 @@ import org.libvirt.jna.SecretPointer; import com.sun.jna.Native; import com.sun.jna.NativeLong; +import com.sun.jna.ptr.LongByReference; +import com.sun.jna.Pointer; +import java.nio.ByteBuffer; /** * A secret defined by libvirt @@ -106,12 +109,16 @@ public class Secret { /** * Fetches the value of the secret - * + * * @return the value of the secret, or null on failure. */ - public String getValue() throws LibvirtException { - String returnValue = libvirt.virSecretGetValue(VSP, new NativeLong(), 0); + public byte[] getValue() throws LibvirtException { + LongByReference value_size = new LongByReference(); + Pointer value = libvirt.virSecretGetValue(VSP, value_size, 0); processError(); + ByteBuffer bb = value.getByteBuffer(0, value_size.getValue()); + byte[] returnValue = new byte[bb.remaining()]; + bb.get(returnValue); return returnValue; } diff --git a/src/main/java/org/libvirt/jna/Libvirt.java b/src/main/java/org/libvirt/jna/Libvirt.java index b1e53a2..f53199d 100644 --- a/src/main/java/org/libvirt/jna/Libvirt.java +++ b/src/main/java/org/libvirt/jna/Libvirt.java @@ -330,7 +330,7 @@ public interface Libvirt extends Library { public int virSecretGetUUID(SecretPointer virSecretPtr, byte[] uuidString); public int virSecretGetUUIDString(SecretPointer virSecretPtr, byte[] uuidString); public String virSecretGetUsageID(SecretPointer virSecretPtr); - public String virSecretGetValue(SecretPointer virSecretPtr, NativeLong value_size, int flags); + public Pointer virSecretGetValue(SecretPointer virSecretPtr, LongByReference value_size, int flags); public String virSecretGetXMLDesc(SecretPointer virSecretPtr, int flags); public SecretPointer virSecretLookupByUsage(ConnectionPointer virConnectPtr, int usageType, String usageID); public SecretPointer virSecretLookupByUUID(ConnectionPointer virConnectPtr, byte[] uuidBytes); -- 1.7.9.5

[libvirt] [PATCH] qemu: Always set auth_supported for Ceph disks.
by Wido den Hollander 05 Jul '12

05 Jul '12

Recently the Ceph project defaulted auth_supported from 'none' to 'cephx'. When no auth information was set for Ceph disks this would lead to librados defaulting to 'cephx', but there would be no additional authorization information. We now explicitly set auth_supported to none when passing down arguments to Qemu.
