[libvirt] [PATCH Repost] esx: Allow 'lsisas1068' as SCSI controller type
by Matthias Bolte 08 Apr '10

08 Apr '10

Extend tests to cover all SCSI controller types and document the new type. The lsisas1068 SCSI controller type was added in ESX 4.0. The VMX parser reports an error when this controller type is present. This makes virsh dumpxml fail for every domain that uses this controller type. This patch fixes this and adds lsisas1068 to the list of accepted SCSI controller types. Reported by Jonathan Kelley. --- This is a repost of this patch [1]. DanPB pointed out that the ESX driver is currently abusing the <driver> element to expose the SCSI controller type. Now we have the <controller> element to explicitly model stuff like SCSI controllers in the domain XML config. The ESX driver doesn't support this yet. Also there is currently no way to express the SCSI controller type in the <controller> element. Something like the model attribute for NICs need to be added here too. So I'd like to push this patch now in order to have the immediate problem of failing virsh dumpxml fixed in libvirt 0.8.0. I already got asked offlist when this problem will be fixed.

[libvirt] [PATCH] Avoid searching for windres when not building for cygwin or mingw.
by Diego Elio Pettenò 08 Apr '10

08 Apr '10

Just checking for a windres tool might hit even on Linux systems when building for Linux (e.g.: when using Gentoo and having built binutils with multitarget support), and will then fail to link properly at the end of the build. Check the host string before deciding whether to look for windres or not. --- configure.ac | 9 +++++++-- 1 files changed, 7 insertions(+), 2 deletions(-) diff --git a/configure.ac b/configure.ac index 29c6396..e6122b9 100644 --- a/configure.ac +++ b/configure.ac @@ -1676,8 +1676,13 @@ AC_SUBST([CYGWIN_EXTRA_PYTHON_LIBADD]) AC_SUBST([MINGW_EXTRA_LDFLAGS]) dnl Look for windres to build a Windows icon resource. -AC_CHECK_TOOL([WINDRES], [windres], [no]) -AM_CONDITIONAL([WITH_WIN_ICON], [test "$WINDRES" != "no"]) +case "$host" in + *cygwin* | *mingw* ) + AC_CHECK_TOOL([WINDRES], [windres], []) + ;; +esac + +AM_CONDITIONAL([WITH_WIN_ICON], [test "$WINDRES" != ""]) -- 1.6.6.1

[libvirt] [PATCH] nwfilters: Test suite for checking created firewall entries
by Stefan Berger 08 Apr '10

08 Apr '10

This patch adds new test cases to the existing nwfilter test program and adds a test script that must be run while a VM is running. This test script verifies that input network filter XML creates expected user-defined tables and rules on ebtables, iptables & ip6tables layer and verifies their content against expected content. The idea is that these tools always return exactly the same output when displaying the content of a user-defined table so that the diff tool can be used for simple text comparison. All supported protocols have at least one test case. This test program is not run automatically since it requires a running VM. For all tests to pass the previously posted ICMP fix patch must be applied.

[libvirt] [PATCH] Avoid a race when restoring a qemu domain.
by Laine Stump 08 Apr '10

08 Apr '10

This patch adds a 1 second sleep after telling qemu to start the restore operation and before telling qemu to start up the CPUs. Without this sleep, my hardware would end up with the CPUs started before the restore was started, leading to random (but never good) behavior. Apparently this is caused by slow hardware, as I haven't heard of anyone else experiencing this problem. A sleep is a very inelegant way to eliminate the problem, but it's apparently the only way currently available to us. Note that sleep durations as low as 250msec were successful in eliminating the bad behavior; I made it 1 sec. just for extra safety. --- src/qemu/qemu_driver.c | 7 +++++++ 1 files changed, 7 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 60fa95a..1270c84 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -5965,6 +5965,13 @@ static int qemudDomainRestore(virConnectPtr conn, /* If it was running before, resume it now. */ if (header.was_running) { qemuDomainObjPrivatePtr priv = vm->privateData; + + /* pause 1 second to allow qemu time to start the restore, + * otherwise it may start the CPUs before the restore, and end + * up in a "nondeterminate" state. + */ + usleep(1000000); + qemuDomainObjEnterMonitorWithDriver(driver, vm); if (qemuMonitorStartCPUs(priv->mon, conn) < 0) { if (virGetLastError() == NULL) -- 1.6.6.1

[libvirt] [PATCH v2] nwfilter: Support for learning a VM's IP address
by Stefan Berger 08 Apr '10

08 Apr '10

Since v1, I have made the following changes: - remove unneeded include files - created a new ATTRIBUTE_PACKED in internal.h (please check) - added libpcap to rpm spec file (not built via rpm) - added 2 flags for the type of traffic to be used to detect the IP address of a VM: DETECT_DHCP & DETECT_STATIC. Now if DETECT_DHCP is chosen, temporary filtering rules are applied on the VM's interface that allow the VM to only send and receive DHCP traffic (optionally restricted to a certain DHCP server) until the actual rules are then applied. In that case the libpcap uses a filter that restricts packets the thread received to DHCP Response traffic. The function to request the learning of the IP address is currently invoked with both flags set, but either one by itself works. A user should consciously configure the VM that triggers that for example DETECT_DHCP is to be used alone since in that case a statically configured interface in the VM will not be able to communicate at all. Now the following ways for learning the IP address parameter are available: - explicitly provided IP address by user as filter parameter - snooping of DHCP OFFERs from a specific DHCP server - snooping of DHCP OFFERs from any server - snooping of any traffic from the VM indicating its IP address This patch implements support for learning a VM's IP address. It uses the pcap library to listen on the VM's backend network interface (tap) or the physical ethernet device (macvtap) and tries to capture packets with source or destination MAC address of the VM and learn from DHCP Offers, ARP traffic, or first-sent IPv4 packet what the IP address of the VM's interface is. This then allows to instantiate the network traffic filtering rules without the user having to provide the IP parameter somewhere in the filter description or in the interface description as a parameter. This only supports to detect the parameter IP, which is for the assumed single IPv4 address of a VM. There is not support for interfaces that may have multiple IP addresses (IP aliasing) or IPv6 that may then require more than one valid IP address to be detected. A VM can have multiple independent interfaces that each uses a different IP address and in that case it will be attempted to detect each one of the address independently. So, when for example an interface description in the domain XML has looked like this up to now: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'> <parameter name='IP' value='10.2.3.4'/> </filterref> </interface> you may omit the IP parameter: <interface type='bridge'> <source bridge='mybridge'/> <model type='virtio'/> <filterref filter='clean-traffic'/> </interface> Internally I am walking the 'tree' of a VM's referenced network filters and determine with the given variables which variables are missing. Now, the above IP parameter may be missing and this causes a libvirt-internal thread to be started that uses the pcap library's API to listen to the backend interface (in case of macvtap to the physical interface) in an attempt to determine the missing IP parameter. If the backend interface disappears the thread terminates assuming the VM was brought down. In case of a macvtap device a timeout is being used to wait for packets from the given VM (filtering by VM's interface MAC address). If the VM's macvtap device disappeared the thread also terminates. In all other cases it tries to determine the IP address of the VM and will then apply the rules late on the given interface, which would have happened immediately if the IP parameter had been explicitly given. In case an error happens while the firewall rules are applied, the VM's backend interface is 'down'ed preventing it to communicate. Reasons for failure for applying the network firewall rules may that an ebtables/iptables command failes or OOM errors. Essentially the same failure reasons may occur as when the firewall rules are applied immediately on VM start, except that due to the late application of the filtering rules the VM now is already running and cannot be hindered anymore from starting. Bringing down the whole VM would probably be considered too drastic. While a VM's IP address is attempted to be determined only limited updates to network filters are allowed. In particular it is prevented that filters are modified in such a way that they would introduce new variables. A caveat: The algorithm does not know which one is the appropriate IP address of a VM. If the VM spoofs an IP address in its first ARP traffic or IPv4 packets its filtering rules will be instantiated for this IP address, thus 'locking' it to the found IP address. So, it's still 'safer' to explicitly provide the IP address of a VM's interface in the filter description if it is known beforehand.
