[PATCH] [Kimchi] Bug fix: Convert CPU and memory values to number before doing any data validation
by Aline Manera 26 Apr '16

26 Apr '16

The value entered for CPUs must not be greater than maximum CPUs value; and the value entered for memory must not be greater than the maximum memory value. But the input boxes return the data in string format which may cause issues while doing data validation. So convert the inputed values to number to do the input validation.

[PATCH][Wok] Return collection list without resource with lookup problems
by Rodrigo Trujillo 25 Apr '16

25 Apr '16

When a collection receives a GET request, it is going to fetch all resources names, in a list, and perform a lookup for each resource, building the return list with all data. There is a potencial race condition problem in this approach. If a given resource is removed between list of names creation and its lookup call, wok is going to fail and the exception is not treated. This patch fix this problem catching the exception, logging the problem and completing the GET request. So, the resource with problem is discarted and other resources are returned.

Edit virtual network feature Pre-requisite: - Virtual network is stopped - Virtual network "default" is not editable *** BACKEND *** ### Resource: Network **URI:** /plugins/kimchi/networks/*:name* **Methods:** * **UPDATE**: Update a Network * name: The name of the Network * subnet: Network segment in slash-separated format with ip address and prefix * dhcp: DHCP services on the virtual network is enabled. * start: start boundary of a pool of addresses to be provided to DHCP clients. * end: end boundary of a pool of addresses to be provided to DHCP clients. * interfaces: An array of bridge network interfaces that belongs to this network All traffic on this network will be bridged through the first interface. The interface is a bridge or ethernet/bonding device. * vlan ID Not all attributes are required for all networks types. *** FRONTEND *** * Add new option Edit to Actions menu under Virtualization/Network tab, enabled only for stopped networks * When clicked, this option will open a new window for editing that virtual network, with the following fields. Based on network type, some of below fields may be disabled: Type: just a label describing the network type, not changeable. Name: all types of virtual network can be renamed Interfaces: attach/detach interfaces (enabled for VEPA) or change interface (for macvtap, bridged) Subnet/DHCP range: two IP fields: start, end (enabled for NAT, isolated) VLAN id: integer field (enabled for bridged networks) -- Lucio Correia Software Engineer IBM LTC Brazil

[PATCH V4] [Kimchi 0/3] Issue #372: Add support to netboot installation.

From: Paulo Vital <pvital(a)linux.vnet.ibm.com> V4: * Changed API of source_media to be a dictionary with type and path * Adapted source code to the new API V3: * set network as third default option to boot order V2: * Adapted patch to new template API (automatic detection of cdrom) V1: This patchset adds support in backend to create templates and guests to netboot without setting a cdrom path or URL as image to install. Once created a guest to boot via network, the guest will request DHCP/TFTP/(NFS/HTTP/FTP) network installation servers to download the configured images and start the install.

- Using localhost was making the feature test too slow, due to use IPv6 by default in systems that has IPv6 enabled but not properly configured. For example, strace shows several attempts to send data to a socket, being droped when timed out: sendto(4, "W\34\326\267\0\0\0\0\0\0\0\2\0\1\206\240\0\0\0\4\0\0\0\3\0\0\0\0\0\0\0\0"..., 84, 0, {sa_family=AF_INET6, sin6_port=htons(111), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 84 poll([{fd=4, events=POLLIN}], 1, 15000) = 0 (Timeout) sendto(4, "W\34\326\267\0\0\0\0\0\0\0\2\0\1\206\240\0\0\0\4\0\0\0\3\0\0\0\0\0\0\0\0"..., 84, 0, {sa_family=AF_INET6, sin6_port=htons(111), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 84 poll([{fd=4, events=POLLIN}], 1, 15000) = 0 (Timeout) sendto(4, "W\34\326\267\0\0\0\0\0\0\0\2\0\1\206\240\0\0\0\4\0\0\0\3\0\0\0\0\0\0\0\0"..., 84, 0, {sa_family=AF_INET6, sin6_port=htons(111), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 84 poll([{fd=4, events=POLLIN}], 1, 15000) = 0 (Timeout) sendto(4, "W\34\326\267\0\0\0\0\0\0\0\2\0\1\206\240\0\0\0\4\0\0\0\3\0\0\0\0\0\0\0\0"..., 84, 0, {sa_family=AF_INET6, sin6_port=htons(111), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 84 poll([{fd=4, events=POLLIN}], 1, 15000) = 0 (Timeout) Both cases are similar: * showmount --no-headers --exports localhost * showmount --no-headers --exports ::1 So, passing 127.0.0.1 we are explicitly requiring a IPv4 connection and that will speed up the feature test *as well as* return the correct result, not a simply timeout: sendto(4, "W\37\256\365\0\0\0\0\0\0\0\2\0\1\206\240\0\0\0\2\0\0\0\3\0\0\0\0\0\0\0\0"..., 56, 0, {sa_family=AF_INET, sin_port=htons(111), sin_addr=inet_addr("127.0.0.1")}, 16) = 56 poll([{fd=4, events=POLLIN}], 1, 15000) = 1 ([{fd=4, revents=POLLERR}]) recvmsg(4, {msg_name(16)={sa_family=AF_INET, sin_port=htons(111), sin_addr=inet_addr("127.0.0.1")}, msg_iov(1)=[{"W\37\256\365\0\0\0\0\0\0\0\2\0\1\206\240\0\0\0\2\0\0\0\3\0\0\0\0\0\0\0\0"..., 56}], msg_controllen=48, [{cmsg_len=48, cmsg_level=SOL_IP, cmsg_type=IP_RECVERR, {ee_errno=111, ee_origin=2, ee_type=3, ee_code=3, ee_info=0, ee_data=0, offender={sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("127.0.0.1")}}}], msg_flags=MSG_ERRQUEUE}, MSG_ERRQUEUE) = 56 Signed-off-by: Jose Ricardo Ziviani <joserz(a)linux.vnet.ibm.com> --- model/featuretests.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/model/featuretests.py b/model/featuretests.py index 23e7eeb..2b680c3 100644 --- a/model/featuretests.py +++ b/model/featuretests.py @@ -148,7 +148,7 @@ class FeatureTests(object): @staticmethod def libvirt_support_nfs_probe(conn): def _get_xml(): - obj = E.source(E.host(name='localhost'), E.format(type='nfs')) + obj = E.source(E.host(name='127.0.0.1'), E.format(type='nfs')) xml = ET.tostring(obj) return xml try: -- 1.9.1
